Abstract
Inventia se refera la un procedeu de preparare a stearatilor metalici, prin care o solutie apoasa de acid stearic se trateaza la temperatura de 70...80 degree C cu o solutie de hidroxid de sodiu purificata cu carbune vegetal, timp de 2h...3h, dupa care se adauga o solutie diluata continînd sarurile metalelor, respectiv în prealabil purificata cu apa oxigenata si carbune vegetal mentinînd temperatura 2...3h la 75 degree C, se spala cu apa demineralizata prin decantare, se centrifugheaza si se marunteste în stare umeda, apoi se usuca si se macina.The invention relates to a process for the preparation of metal stearates by which an aqueous solution of stearic acid is treated at a temperature of 70 ... 80 ° C with a solution of sodium hydroxide purified with vegetable carbon for 2 hours. 3h, after which a diluted solution containing the metal salts, previously purified with hydrogen peroxide and vegetal charcoal, is maintained, maintaining the temperature of 2 ... 3h at 75 ° C, washed with demineralized water by decantation, centrifuged and shrunk wet, then dry and grind.
