| 应用领域 | Uses: Used as an intermediate in chemical manufacturing、[HSDB] Continuously manufactured and processed in closed systems and essentially used 100% as an intermediate、[OECD SIDS]、CHEM INT FOR 3、4-DICHLORO-1-BUTENE (A CHLOROPRENE INT)、ADIPONITRILE (A HEXAMETHYLENEDIAMINE INT) & CHEM INT FOR 1、4-BUTANEDIOL (NON-US USE).、1、4-Dichloro-2-butene is used for resolving oil-in-water emulsions.、Used as an intermediate in the production of chloroprene ... is a starting material in the production of adiponitrile、butane-1、4-diol、and tetrahydrofuran.、From 1951 to 1983 DuPont operated a butadiene chlorination process ... the intermediate 1、4-dichloro-2-butene was converted to 3-hexenedinitrile ... and then hydrogenated to adiponitrile.、Industry Uses: Monomers、Methods of Manufacturing: The isomers 3、4-dichlorobutene、cis-1、4-dichlorobutene & trans-1、4-dichlorobutene are produced、by the reaction of chlorine & butadiene、& when the mixture is heated、an equilibrium results. The residue resulting from removal of the 3、4-isomer ... is normally used without further separation.、Chlorination of butadiene in chloroform or carbon disulfide below 0 °C gives a mixture of 3、4-dichloro-1-butene and 1、4-dichloro-2-butene、in a ratio of about 2:1、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.、Dichlorobutene isomers、Formulations、Preparations: 1、4-DICHLOROBUTENE AVAILABLE IN USA CONTAINS 95-98% TRANS ... & 2-5% CIS ISOMER.、4-Dichlorobutene、technical grade、85%、is a mixture of both cis- and trans- isomers.、Consumption Patterns: ESSENTIALLY 100% AS A CHEM INT FOR 3、4-DICHLORO-1-BUTENE & ADIPONITRILE、U.S. Production: 2023: 2、700、000 lb、2022: 3、100、2021: 2、800、2020: 2、400、(1977) AT LEAST 4.54X10+9 G、(1982) PROBABLY GREATER THAN 4.54X10+6 G、General Manufacturing Information: Synthetic Rubber Manufacturing、2-Butene、4-dichloro-: ACTIVE、In the presence of catalyst (at 100 °C)、a liquid mixture of dichlorobutenes equilibrates to a composition of 21% 3、4-dichloro-1-butene、and 7% cis-1、4-、and 72% trans-1、4-dichloro-2-butene. The vapor phase above the liquid contains 52、6、and 42%、respectively、of the isomers. |
