| titleOfInvention | Method of enhancing chromaticity of triethanolamine |
| abstract | FIELD: chemistry. n SUBSTANCE: method involves addition of a phosphorus-containing compound in liquid phase to triethanolamine, where the phosphorus-containing compound is phosphane and/or a compound which releases phosphane, selected from phosphonium halide or metallophosphide which contains group IA, IIA, IIIA or IIB metals in an amount of at least 0.001 wt % while heating and subsequent separation of pure triethanolamine from the additive or additives. Phosphane usually refers to PH 3 , P 2 H 4 or P 4 H 6 . Phosphide refers to lithium phosphide, sodium phosphide, potassium phosphide, magnesium phosphide, calcium phosphide, aluminium phosphide, indium phosphide and/or zinc phosphide. Triethanolamine is mixed with phosphane and/or a compound which releases phosphane in amount of 2 wt % (in terms of pure triethanolamine) before and/or during distillation of the triethanolamine. The desirable time for treatment with the additive is at least 5 minutes at temperature ranging from 40 to 250°C. Triethanolamine may contain water in amount of 0.01-20 wt % (in terms of pure triethanolamine). The invention also relates to triethanolamine containing at least 0.001 (in terms of pure triethanol) of the mass of phosphane and/or a compound which releases phosphan selected from phosphonium halide or metallophosphide containing group IA, IIA, IIIA or IIB metals, which is the initial mixture for enhancing chromaticity. n EFFECT: enhanced chromaticity of triethanolamine. n 17 cl |
