Пример 2. Из 20 мл хлорсульфоновой кислоты и 10 г адамантана при выдерживании реакционной смеси в течение 4 суток в услови х , аналогичных приведенным в примере 1, получают 13,67 г 1,3-дихлорадамантана (выход 91%). Степень частоты по данным ГЖХ 97,7%.Example 2. From 20 ml of chlorosulfonic acid and 10 g of adamantane while keeping the reaction mixture for 4 days under conditions similar to that shown in example 1, 13.67 g of 1,3-dichloroamantane are obtained (yield 91%). The degree of frequency according to GLC 97.7%.
Таким образом, подобранные услови (весовое соотношение адамантаиа и хлорсульфоновой кислоты, температура и продолжительность ведени реакции) позвол ют получатьThus, the selected conditions (the weight ratio of adamanty and chlorosulfonic acid, the temperature and the duration of reaction) make it possible to obtain
чистый 1,3-дихлорадамантан с высоким выходом .pure 1,3-dichloradamantane with high yield.
Предмет изобретени Subject invention
Способ получени 1,3-дихлорадамантана путем хлорировани адамантана избытком хлорсульфоновой кислоты с последующим выделением целевого продукта, отличающийс тем, что, с целью повышени селективности процесса и увеличени выхода продукта, хлорсульфоновую кислоту берут в трех-четырехкратном весовом избытке, и процесс ведут при 15- 25°С в течение 72-120 час.The method of obtaining 1,3-dichlororadantane by chlorinating adamantane with an excess of chlorosulfonic acid followed by isolation of the target product, characterized in that, in order to increase the selectivity of the process and increase the yield of the product, chlorosulfonic acid is taken in a three to fourfold weight excess, and the process is carried out at 15- 25 ° C for 72-120 hours.
