• CHEMICAL INTERMEDIATE FOR HEXAMETHYLENEDIAMINE & CHLOROPRENE
• TRANS-1,4-DICHLOROBUTENE IS ... CONSUMED CAPTIVELY IN ... /JAPAN/ TO PRODUCE 1,4-BUTANEDIOL BY HYDROLYSIS FOLLOWED BY HYDROGENATION.
• Occurs as an intermediate in the production of chloroprene...is a starting material in the production of adiponitrile, butane-1,4-diol, and tetrahydrofuran
• Obtained in a yield of 93% by chlorination of butadiene in the vapor phase at 300-350 °C...dichlorobutene isomers are also formed in the oxychlorination of C4 cracking fractions containing butadiene and isobutene /cis and trans-isomers/
• The preparation of trans-1,4-dichlorobutene by chlorination of butadiene was first reported in 1930 (Muskat IE, Northrup HE; Studies of conjugated systems, V The preparation and chlorination of butadiene; J Amer Chem Soc 52: 4043-55 (1930)), & this method is used for its commercial production.
• Technical material with an 85% composition of the trans-isomer, the remainder is predominantly the cis-isomer
