PROCESS FOR PRODUCING α,ω-CHLOROALKANES (CHLOROHYDRINS) Russian patent published in 2006 - IPC C07C31/36 C07C29/62 

FIELD: industrial organic synthesis.

SUBSTANCE: invention relates to production of α,ω-chloroalkanes (chlorohydrins), which are employed for production of diol monoethers used in varnish-and-paint industry in production of polyoxyamides, such as Niplon-2 varnish, designed for impregnation of glass-carbon fabrics to impart heat-retention properties as well as intermediates in production of dyes, halogen-substituted polymers, pharmaceutics, polymerization catalysts, plasticizers. Process of invention comprises catalytic chlorination of diols with carbon tetrachloride in presence of 0.1 mmole Mo(CO)6 at 120-140°C for 3-8 h, wherein molar ratio Mo(CO)6/diol/CCl4 = 1:200:1000.

EFFECT: reduced consumption of catalyst and reaction time, increased selectivity, reduced expenses, and simplified technology.
