Цель изобретени - улучшение детергентно-диспергирующих свойств и снижение зольности присадки.The purpose of the invention is to improve the detergent-dispersant properties and reduce the ash content of the additive.
Технологи предлагаемого способа заключаетс в том, что осерненный алкилфенол подвергают формальдегидной конденсации в щелочной среде, а затем обрабатывают гидроокисью кальци . Ре акцию конденсации провод т в присутствии мае.ч. гидроокиси кальйи в течение 1-1,5 ч при 65-95°С.The technology of the proposed method consists in the fact that sulfonated alkylphenol is subjected to formaldehyde condensation in an alkaline medium, and then treated with calcium hydroxide. The condensation reaction is carried out in the presence of mac. calcium hydroxide for 1-1.5 h at 65-95 ° C.

сушке. После отделени от механичес-; ких примесей центрифугированием получаетс готовый продукт. Присадка, полученна предлагаемым способом, названа ИХП-110, представл ет собой кальциевую соль бис-(метилолалкилфенол )-дисульфида в растворе минерального масла (80% ),drying. After separation from the mechanical; By centrifuging, the finished product is obtained. The additive obtained by the proposed method, called ICP-110, is a calcium salt of bis- (methylolalkylphenol) disulfide in a mineral oil solution (80%),
Результаты испытаний присадки ИХП-110 в. сравнении с известной приведены в таблице.The test results of additives IHP-110 in. comparison with the known are given in the table.
Как видно из данных таблицы, присадка ИХП-110, име на 20-30 мг-КОН/г большее щелочное число, и на 28-32% меньшуй зольность, не уступает известной -по моющим и антикоррозионным свойствам и одновременно улучшает детергентно-диспергирующие и противоокислительные свойства известной.As can be seen from the table, the additive IHP-110, having a 20-30 mg-KOH / g higher base number and 28-32% less ash, is not inferior to the known detergent and anti-corrosion properties and simultaneously improves detergent-dispersant and antioxidant properties known.
