COMPOSITE EMULSIFIER FOR PRODUCTION OF EMULSION EXPLOSIVES AND A METHOD FOR PRODUCTION THEREOF Russian patent published in 2019 - IPC B01F17/36 C06B23/00 

FIELD: chemistry.

SUBSTANCE: invention relates to emulsifying compositions used in production of industrial emulsion explosives. Emulsifier is a product of reaction of mixed triglycerides of saturated and unsaturated fatty acids C_6:0-C_24:0, contained in vegetable oils, with alkanolamine or a mixture of alkanolamines, which is a mixture of long-chain fatty organic limit and unsaturated acids, their alkanolamines, N-acylated fatty acids (and/or esters of fatty organic limit and unsaturated acids with a trialkanolamine), mono- and diglycerides. Emulsifier is obtained by mixing vegetable oil with alkanolamine or mixture of alkanolamines in molar ratio of 1:1.5–2 respectively at temperature of 120–140 °C in the presence of a homogeneous catalyst with subsequent acidification of the reaction mass.

EFFECT: emulsifier has high operational characteristics, low toxicity and wide raw material base for production, as well as a simplified method for its production, which improves safety and environmental friendliness of its production.
