Изобретение относитс к способу получени нового производного п-карбоксифенилгексафторизопропанола , а именно его хлорангидрида .This invention relates to a process for the preparation of a new derivative of p-carboxyphenylhexafluoroisopropanol, namely its acid chloride.
Йснользу известный прием введени хлора с помощью тионилхлорида в присутствии каталитических количеств пиридина, получают хлорангидрид п-карбоксифенилгексафторизопронанола , содержащий незамещенную гидроксильную группу, хот известно замещение гидроксильной группы на хлор с помощью тионилхлорида.Using a known method of introducing chlorine with thionyl chloride in the presence of catalytic amounts of pyridine, p-carboxyphenylhexafluoroisophenanol chloride, containing an unsubstituted hydroxyl group, is obtained, although it is known to replace the hydroxyl group with chlorine with thionyl chloride.
Предлагаемый снособ позвол ет получать хлорангидрид п-карбоксифенилгексафторизопропанола , вл юп 1,ийс монометром дл производства высокоэластичных и термостойких материалов.The proposed snoot allows to obtain p-carboxyphenylhexafluoroisopropanol chloride, which is Jup 1, a monomer for the production of highly elastic and heat-resistant materials.
Способ заключаетс в том, что п-карбоксифенилгексафторизопропанол .кип т т с тионилхлоридом в присутстви каталитических The method consists in the fact that p-carboxyphenylhexafluoroisopropanol. Boil with thionyl chloride in the presence of catalytic
.количеств пиридина и продукт выдел ют изв е CTIH ым н п р 11 е м а м и.The amounts of pyridine and the product are isolated with CTIH in a n 11 emam.
Пример. 11 г д-карбоксифенилгексафторизопронанола смещивают с 18,7 мл тиоиилхлорида , добавл ют каталитическое количество пиридина п кип т т с тионилхлоридом в течение 5 час. Избыток тиоиилхлорида отгон ют , остаток перегон ют в вакууме. Выход 7,48 г (63,4%), т. кип. 103-104°С/10 мм рт. ст.Example. 11 g of d-carboxyphenylhexafluoroisopronanol is displaced from 18.7 ml of thioyl chloride, a catalytic amount of pyridine p is added and boiled with thionyl chloride for 5 hours. Excess thioyl chloride is distilled off, the residue is distilled in vacuo. The yield of 7.48 g (63.4%), t. Kip. 103-104 ° C / 10 mmHg Art.
