1,4-Butanediol History

1,4-butanediol was first prepared in 1890 by acid hydrolysis of N,N'-dinitro- 1,4-butanediamine.
Other early preparations were by reduction of succinaldehyde or succinic esters and by saponification of the diacetate prepared from 1,4-dihalobutanes. Catalytic hydrogenation of butynediol, now the principal commercial route, was first described in 1910.

1,4-Butanediol Analytical Methods

Butanediol is specified as 99.5% minimum pure, determined by gas chromatography, solidifying at 19.6 ℃ minimum. Moisture is 0.04% maximum, determined by Karl Fischer analysis (directly or by a toluene azeotrope).

1,4-Butanediol Specification

The IUPAC name of this chemical is butane-1,4-diol. With the CAS registry number 110-63-4 and EINECS registry number 203-786-5, it is also named as 1,4-Butanediol. In addition, the molecular formula is C₄H₁₀O₂ and the molecular weight is 90.121. It is odorless colorless liquid or solid (depending upon temperature).This colorless viscous liquid is derived from butane by placement of alcohol groups at each end of the chain. It is one of four stable isomers of butanediol. What's more, it is incompatible with strong oxidizing agents, mineral acids, acid chlorides, acid anhydrides. It should be stored in a cool, ventilated and dry place. The storage place must stay away from oxidant and water.

Uses of 1,4-Butanediol: it can be used in the production of THF, γ-butyllactone and butanediol polyp-phthalate. It also can be used as chain extender and raw materials of polyester to produce polyurethane elastomer and soft polyurethane foam plastics. It has good absorbency and increased flexibility, can make gelatin softener and SAP. In addition, it can prepare derivative of N-methyl pyrrole, N-vinyl pyrrole and other pyrrole, also can be used in preparation of vitamin B6, pesticides and herbicides. What's more, it can react with butylamine to get 1-butyl-pyrrolidine. This reaction will need catalyst RuCl3. The reaction time is 5 hours at reaction temperature of 220 °C. The yield is about 36%.
