PROCESS FOR PREPARING PHOSPHORUS-AND SULFUR CONTAINING BIO-AND FIRE-RESISTANT AGENT Russian patent published in 1996 - IPC

Abstract RU 2067582 C1

FIELD: chemical and biological industries. SUBSTANCE: claimed process for preparing not fully substituted esters of fatty alcohols and phosphorus and sulfur containing acids. Such esters are widely used as additives to cutting fluids, combustion inhibitors, plasticizers, and additives to mineral oils, and the like. The claimed process comprises esterifying phosphoric and sulfurous acid chlorides with fatty alcohols and hydrolizing the resulting monoalkyl chloroesters with water to obtain the desired products. The claimed process uses thionyl chloride production waste as phosphorus and sulfur containing raw material and C10-C16-fatty alcohols. Esterification is carried out at 30-80 C and phosphorus oxychloride to alcohol molar ratio of 1:(1.1-1.4). Hydrolysis is carried out at 60-90 C and esterified dichlorides to water molar ratio of 1:(2.2-2.7). EFFECT: more efficient preparation process. 2 tbl
