Epichlorohydrin in the last week price cuts, this week offer rose, the venue atmosphere again chaos for a while, but soon also found the main line, into the consolidation period. The current East China region to discuss the mainstream in the 8200 yuan / ton in East China received to the downstream factory can be purchased to 8,100 yuan / ton of supply, some traders offer slightly higher.

Speaking of epichlorohydrin market outlook, as early as before, the industry will have to focus on the main bearish. However, the main factory in the normal implementation of the contract did not produce inventory of the backlog, and the supply of glycerol law is also less, exclusive market conditions also have absolute right to speak, so long-term operation to stabilize the main. And the reason why the weekly offer so the decline in the range, on the one hand because the offer and the real gap is too large, the factory in order to narrow its spread, on the other hand is to continue to suppress the restart of the glycerine factory. Yihai Kerry device after a long period of parking to resume the start, although the load is not high, but also more or less to seize market share. But the more important reason is because the downstream demand is significantly weakened, although the factory will not expand the library, will try to consider the feeling of the downstream, in their own profit under the considerable concessions given to the downstream. However, after the price cuts, the parties bearish mood thicker, and their purchasing enthusiasm is not high, to be down under the mood to wait and see.

The factory this week will only be able to offer a slight increase of 100 yuan / ton, but the real single ex-factory price did not significantly fluctuate, which is the market and the downstream release of a price will not fall signal. But this did not change the industry is not the state of high emotions, accompanied by the parties on the market, for the time being steady operation. Downstream continue to maintain a small single just need to take with the take, buy gas is still flat. But in the previous field there will be rumors of the factory to the big price is low, but the message has not been implemented, the parties are also more to wait and see. After all, there is a low-cost presence, high prices will gradually appear weak, talk tends to low-end finishing. The current market situation is still clear in a trace of confusion. Weak demand will continue, the attitude of the procurement of epichlorohydrin will not have much change. The main factory shipments and the increase in inventory is more concerned about the focus of the industry, other small factories in the lack of competitiveness will follow the pace of the main factory, short-term changes in the market space is limited.

May 18 (Thursday) caprolactam price of 11727.27 yuan / ton, compared with May 17 rose 145.45 yuan / ton, compared with the overall increase of 77.27 yuan / ton, or 0.66%. This is the first time since May’s rebound.

Quotes analysis

This week, caprolactam fell after the first rise, the overall trend was wide shocks. May 18 (Thursday) by the Sinopec pure benzene raised boost, caprolactam spot market up significantly, LUBON INDUSTRY CO., LTD and other major domestic production quotations rose 200 yuan / ton to 11,500 yuan / ton. With the enthusiasm of the downstream goods to increase, the market began to bottom out, the current mainstream of the liquid market in East China reference 11200-11400 yuan / ton, acceptance to the price; solid market mainstream reported 13,000 yuan / ton, high-end products in East China reported 13,500 Yuan / ton or so. But subject to poor demand for the terminal, the market pull up power is limited.

This week as the downstream of the caprolactam PA6 market to pick up, the major polymerization plant offer the focus of steady upward trend, the current East China Conventional spinning mainstream shipping price close to 13,500 yuan / ton cash from mentioning, part of the high-end section of light offer up to But the downstream with more limited; but high-speed spinning shipments are still relatively large, currently around 13000-13500 yuan / ton acceptance, the transaction price is low, the inventory is relatively sufficient.

Forecast

At present, caprolactam market from the cost of support is strong, but subject to the demand side of the weak, the price is difficult to rebound, short-term market will shock consolidation.

L-aspartic acid has a wide range of uses. L-aspartic acid in the medical can be widely used as potassium and other inorganic ions to add fatigue recovery agent, ammonia antidote and amino acid infusion and other drugs; due to a special sweet, can be used as food additives; Amino acid can be made of polyaspartic acid polymer, used as a scale inhibitor, tackifier and surfactant, etc., but also when the use of non-polluting pesticides.

1. Application in the pharmaceutical industry
Aspartic acid (Aspartic acid) is one of the twenty basic amino acids that make up the protein, which has a wide range of applications in biochemical reagents and clinical medicine. As a non-essential amino acid, it can regulate brain and nerve (L-Asp) is widely used as an additive for ammonia antidote, liver function accelerator, fatigue restorative and other additives for the production of various kinds of soft drinks; its racemic Vitamin DL-Aspartic acid (DL-Asp) can be used to synthesize DL-aspartate magnesium salt (pulse stability) for the treatment of heart rate disorders, tachycardia, heart failure, myocardial infarction, angina pectoris, hepatitis and liver Hardening and other diseases.

Potassium magnesium aspartate (PMA) has a strong cell affinity, as a chelating agent and metal ions combined after the separation of slower. In the absence of potassium and magnesium, PMA can be used as a carrier, to promote potassium and magnesium ions easily into the cells, so as to better play their biological role. In addition, PMA can make heart rate disorders disappear or significantly reduced, the total effective rate as high as 94%. DL-aspartic acid can also be used as a raw material for synthetic peptides, and its amino acid substituted derivatives (NMDLA) can be used as drugs for the treatment of neurological diseases and brain diseases.

2. Application in agriculture
Polyaspartic acid derivatives are easily ingested into the roots of plants in the soil and can absorb and enrich elements useful in the soil around the roots such as N, P, K, Ca, Mg, S, №, Cu and Fe , To promote plant growth, it is applicable to all kinds of soil. In addition to direct application, but also can be used for plant seed coating, with the role of improving the germination rate. Polyaspartic acid is a new generation of fertilizer synergist because of its excellent degradation of polyaspartic acid, which can promote plant growth and reduce surface water pollution due to fertilizers. At the same time as polyaspartic acid has a good insecticidal, sterilization and dispersibility, and thus polyaspartic acid for pesticides, both to protect the plant from pests and diseases, but also with other components of pesticide compound, Surface wetting, dispersion, solubilization and penetration, give full play to the efficacy of pesticides.

3. Application in industry
L-aspartic acid can be prepared as polyaspartic acid derivatives (PASP). C. S. Sikes et al. Used a copolymer of polyaspartate, polyglutamic acid salt and other amino acids to inhibit the precipitation of inorganic and organic calcium carbonate. The copolymer had an optimum molecular weight of 3500 to 10,000 and was biodegradable, It can be used as a scale inhibitor for seawater desalination plants or circulating cooling water. C. S. Sikes et al. Also investigated the resistance of the hydrophobic blocked amino acid (peptide) containing a plurality of anions, which has a block structure consisting of 15 aspartic acid units and 8 alanine units Composition, the least effective peptide has five units, two of which are selected from the ionic amino acid groups, the two blocks together do not exceed 120 units; prepared polysuccinimide and long-chain alkylamine The reaction product, which can act as a surfactant in the cleaning agent.

4. Other aspects of the application
L-aspartic acid can also be prepared into a variety of derivatives in the daily chemical applications, such as moisturizing lotion, shampoo and conditioner, etc .; can also be used in dispersants used in pigments and coatings.
