Triethanolaminetriborate solves the problem of low solubility and inclination to crystallisation of the borate component in case of most known technically useful borates. It is a product of the synthesis of boric (III) acid or its anhydride and triethanolamine. It is an exothermic reaction taking place at 114 DEG C in a covered reactor, that allows for oil heating and is fitted with a thermostat, with thermal protection and with water condenser applied in the following reaction: N(CH2CH2OH)3 + 3H3BO3 } N(CH2CH2-O-H2BO2)3 + 3H2O triethanolamine boric acid triethanolaminetriborate or: N(CH2CH2OH)3 + 1,5 B2O3 + 1,5 H2O } N(CH2CH2-O-H2BO2)3 triethanolamine boric acid anhydride triethanolaminetriborate. Application: heat transmission agents, working liquids, hydraulic liquids, biocide and anti-fire protection of material. |
