1,4 butylene glycol - colorless viscous low-volatile liquid with sweetish taste. Let's well dissolve in water, alcohols, acetone, restrictedly we will dissolve on air, benzene chloride, CCl4-it is badly soluble in non-polar solvents.

On chemical properties 1,4 butylene glycol - typical glycol. Forms esters with acids, their anhydrides and acid halides. 1,4 butylene glycol are dehydrogenated in vapor or liquid phase at 200 ° - C (reaction is catalyzed by copper salts on the carrier) with formation of gamma hydroxy butanole acid lactone (exit to 90%).

In chemical industry 1,4 butylene glycol is received:

  • by method to Reppa condensation of acetylene with formaldehyde on the mednovismutovy catalyst (90-100 ° - C-of 0.5-0.6 MPas) with the subsequent hydrogenation of the formed 2-butyn-1,4-diol on the mednonikelkhromovy catalyst (150-160 ° - C-of 20 MPas). Exit about 90%.
  • 1,4 butylene glycol can also be received acetoxylation of butadiene on the palladic catalyst with the subsequent hydrolysis of acetate:

H2C=CH-CH=CH2 + CH3COOH + 1/2O2-> - H3COC(O)CH2CH=CHCH2C(O)OCH3-> - HO(CH2)4OH

  • acetoxylation of propylene to allylacetate with the subsequent hydroformylation, hydrogenation and hydrolysis of intermediate products to 1,4-butandiola-
  • hydrogenation of maleic anhydride in tetrahydrofuran with the subsequent its hydrolysis.



1,4 butylene glycol is applied in production of polyurethane, polyethers (at condensation 1,4 butylene glycols with terephthalic acid are formed polybutylene-terephthalate), effective plasticizers to thermolayers, in receiving gamma hydroxy butanole acid lactone. 1,4 butylene glycol are important as the plasticizer and the moistening agent for gelatin, cellophane, special grades of paper, tobacco.
