Description
(54) СПОСОБ РАФИНИРОВАНИЯ СЫРОГО ГОРНОГО ВОСКА(54) METHOD OF REFINING RAW MOUNTAIN WAX
Дозирование раствора бихромата происходит при отгонке 65% количества воды, введенной вместе с серной кислотой. Бихромат извлекают почти без остатка.Dosing of the dichromate solution occurs when a distillation of 65% of the amount of water introduced with sulfuric acid occurs. Bichromate is extracted with almost no residue.
Результаты приведены в таблице.The results are shown in the table.
кислотное число, мг КОН/г; число омылени , мг КОН/г; эфирное число, мг КОН/г; число, равное числу гидроксилОв, мг КОН/г; точка затвердевани .acid number, mg KOH / g; saponification number, mg KOH / g; ether number, mg KOH / g; a number equal to the number of hydroxyl Ov, mg KOH / g; solidification point.
Таблица показывает, что в обоих рйдах опытов вариант 2, по которому воск эмульгируют быстро, сернокислый раствор бихромата прибавл ют медленно, рафинированный воск получают с самым высоким содержанием кислот воска и самым низким содержанием сложных эфиров и соединений, содержащих гидроксильные группы. В варианте 3 при медленном эмульгировании и быстром прибавлении раствора бихромата получают рафинированный воск с самым низким содержанием кислот воска и самым высоким содержаниемThe table shows that in both types of experiments, option 2, in which the wax was emulsified quickly, sulphate of dichromate was added slowly, refined wax was obtained with the highest content of wax acids and the lowest content of esters and compounds containing hydroxyl groups. In embodiment 3, with slow emulsification and the rapid addition of a solution of dichromate, refined wax is obtained with the lowest content of wax acids and the highest content
сложных эфиров и соединений с гидроксильными группами.esters and compounds with hydroxyl groups.
Предмет изобретени Subject invention
Способ рафинировани сырого горного воока по патенту № 374839, отличающийс тем, что, с целью получени воска с различной степенью очистки, обработку сырого горного воска водным раствором серной кислоты ведут в течение 5-100 мин, а раствор хроматов добавл ют в течение 15-240 мин.The method of refining raw mountain wok according to patent No. 374839, characterized in that, in order to obtain wax with different degrees of purification, the processing of raw mountain wax with an aqueous solution of sulfuric acid is carried out for 5-100 minutes, and the solution of chromates is added within 15-240 min
