Description
90 дают 36,5 г (0,2 моль) аллилоксибензипхлорид и перемешивают при 50 -60°С в течение 4 ч. Смесь промывают водой, фильтруют и подвергают вакуумной перего ке. Получено 44,85 т (84%) вещества. П р и м е р 2. 2-Ал;01Локси-5-метилбензи ловый эфир этилксэнтогеновой кислоты. К 32 г (0,2 моль) этилксанпената кали в растворе изопропилового спирта добавл ют 39,5 г (0,2 моль) 2-аллилокси-5-метилбензилхлорида и перемешивают при 65-70°С в течение 4 ч. Реакционную массу промывают водой, фильтруют и . Получают 48,0 г (85%) вещества. Аллилоксибензиловые эфиры и 2-аллю1окси-5-метилбензиловые эфиры ксантогеновых кислот представл ют собой легкоподвижные укк кост светло-соломенного цвета, хорошо растворимые в органических растворител х: бензоле, зфире, изооктане. Аналогично реакда протекает и с другими ксантогенатами. Анализ полученных эфиров представлен в табл. 1.90 give 36.5 g (0.2 mol) of allyloxybenzyl chloride and stir at 50–60 ° C for 4 h. The mixture is washed with water, filtered and subjected to vacuum distillation. Received 44.85 tons (84%) of the substance. EXAMPLE 2 2-Al; 01 Loxy-5-methylbenzyl ester ethyl xentogenic acid. 39.5 g (0.2 mol) of 2-allyloxy-5-methylbenzyl chloride are added to 32 g (0.2 mol) of potassium ethylxane in a solution of isopropyl alcohol and stirred at 65-70 ° C for 4 hours. The reaction mass is washed water, filtered and. 48.0 g (85%) of the substance are obtained. The allyloxybenzyl esters and the 2-allyoxy-5-methylbenzyl esters of xanthogenic acids are highly mobile, light straw-colored, well soluble in organic solvents: benzene, sfire, isooctane. Similarly, the reaction proceeds with other xanthates. The analysis of the resulting esters is presented in Table. one.
Эффективность замещенных бензиловых эфиров ксантогеновых кислот устанавливаетс путем испытани их в смеси с трансмиссионными маслами ТБ--20.The effectiveness of the substituted benzyl esters of xanthogenic acids is established by testing them in a mixture with transmission oils TB-20.
Исследование противоизносных свойств эфиров ксантогеновых кислот провод т на 4-шариковой машине трени им шариках, диаметром 12,7 мм при скорости скольжени 1400 1400 об/мин.The anti-wear properties of xanthic acid esters were studied on a 4-ball friction machine using balls with a diameter of 12.7 mm and a sliding speed of 1400 1400 rpm.
