Purity 99.9% 1 4-Butanediol CAS NO 110-63-4 Raw Powder

Purity 99.9% Pesticide Intermediates With Name 1,4-Butanediol

1, 4-butanediol (BDO), Pesticide Intermediates, is an important basic organic chemical and fine chemical raw materials, which has a wide range of uses, especially its derivatives are fine chemical products with high added value, widely used as solvents, medicine, cosmetics, plasticizers, curing agents, pesticides, herbicides, artificial leather, fibers, engineering plastics and so on. 1, 4-butanediol is also used in the manufacture of γ-butanolactone (GBL), tetrahydrofuran (THF), N-methylpyrirolidone (NMP) and so on. Since the 1970s, the development of 1, 4-butanediol has been promoted by the rapid development of polyurethane industry and polybutanediol terephthalate (PBT) engineering plastics.

Uses

1,4-Butanediol is widely used. More than half in the United States and Western Europe are used for the production of tetrahydrofuran, followed by the production of γ-butyrolactone and polybutylene terephthalate, the latter is a rapidly developing engineering plastic; 1,4-butanediol is used as an additive Chain agents and polyester raw materials are used in the production of polyurethane elastomers and flexible polyurethane foams; esters made from 1,4-butanediol are good additives for cellulose, polyvinyl chloride, polyacrylates and polyesters. plasticizer. 1,4-Butanediol has good hygroscopicity and flexibility, and can be used as gelatin softener and water-absorbing agent, as a treatment agent for cellophane and other unused paper. It can also be used to prepare N-methylpyrrolidone, N-vinylpyrrolidone and other pyrrolidone derivatives, and also used to prepare vitamin B6, pesticides, herbicides and solvents, plasticizers, lubricants, moisturizing agents for various processes , softness, adhesives and brighteners for the electroplating industry.

Toxicity

Toxic. When attached to diseased or wounded skin or ingested, it initially exhibits anesthesia, causing specific pathological changes in the liver and kidneys, and then sudden death (without prolonged latency) due to central nervous system paralysis. Oral LD50 of white mice is 210-420 mg/kg. Production equipment should be sealed to prevent leakage, and operators should wear protective equipment. People with wounded skin are strictly prohibited from contacting this product.

Packaging

Storage and transportation: It is packaged in aluminum, stainless steel, galvanized iron drums or plastic drums, or in tank trucks according to the regulations for flammable and toxic substances. Because the melting point is as high as 20 ℃, the tank car should be equipped with a heating tube.
