Preparation:

  1. Acetylene method: 1,4-butynediol is made by reacting acetylene and formaldehyde in the presence of Cu-Bi catalyst at 98kPa and 80-95℃. The latter is then catalyzed by nickel skeleton and hydrogenated at 1.372-2.06 MPa, 50-60°C to 1,4-butenedioate, followed by further catalytic hydrogenation with Ni-Cu-Mn/Al2O3 (13.7-20.6 MPa, 120-140°C) to 1,4-butanediol, which is then purified by distillation after removal of metal ions by ion exchange resin. 2. Maleic Anhydride Hydrogenation method 3. Butadiene method Acetyl oxidation reaction of 1,3-butadiene with acetic acid and oxygen to produce 1,4-diacetoxy-2-butene, then hydrogenated and hydrolyzed to make 4. 1,4-dichlorobutene method 1,4-dichlorobutene is an intermediate product of the process of producing chlorobutadiene from butadiene, which is used as raw material, hydrolyzed and hydrogenated to obtain 1,4-butanediol.

 

Uses:

1,4-butanediol is an important organic chemical and fine chemical raw material, and is the basic raw material for the production of polybutylene terephthalate (PBT) engineering plastics and PBT fiber; PBT plastic is one of the five most promising engineering plastics.

1,4 butanediol is the main raw material for the production of tetrahydrofuran, which is an important organic solvent. The polytetramethylene glycol ether (PTMEG) obtained after polymerization is the basic raw material for the production of high-elasticity spandex (Lycra fiber). Spandex is mainly used in the production of high-elasticity knitted products such as advanced sportswear and swimwear.

γ-butyrolactone, a downstream product of 1,4-butanediol, is the raw material for the production of 2-pyrrolidone and N-methylpyrrolidone products, from which a series of high value-added products such as vinylpyrrolidone and polyvinylpyrrolidone are derived, which are widely used in pesticides, pharmaceuticals and cosmetics.

Features and uses:

A liquid tertiary amine catalyst. Can improve foam cure and demolding time. It is an excellent candidate to consider for use in water-NCO reaction in rigid polyurethane foams.

BDMA is typically suitable to replace DMCHA in formulations using a high level of water as blowing or co-blowing agent can reduce surface friability and improve adhesion of foam to substrates.

BDMA promotes the urethane reaction and is commonly used in high-water rigid foam applications to reduce friability. It has a characteristic but low amine odor, and is soluble in water and in most organic solvents.

BDMA is used in flexible slabstock and rigid foam applications.

It promotes the urethane reaction and is commonly used in high-water rigid foam applications to reduce friability.

BDMA is also used for flexible slabstock foam applications.

Storage Information ：

Recommends that our catalysts be stored in a dry and cool area under appropriate ventilation conditions. Each container should be closed tightly to avoid contamination with moisture or other negative influences that could change the products’ performance in the end use.
