Description
Известен способ получени триарилфосфитов взаимодействием треххлористого фосфора с фенолами при нагревании в присутствии .хлористого магни в качестве катализатора.A known method for producing triaryl phosphites by reacting phosphorus trichloride with phenols by heating in the presence of magnesium chloride as a catalyst.
С целью упроидени способа предлагаетс получать триарилфосфиты взаимодействием треххлористого фосфора с фенолами при нагревании в присутствии гетероциклических оснований в качестве катализатора.In order to simplify the process, it is proposed to obtain triaryl phosphites by reacting phosphorus trichloride with phenols by heating in the presence of heterocyclic bases as a catalyst.
Пример 1. Три-(2,4-дихлорфенил) фосфит .Example 1. Three- (2,4-dichlorophenyl) phosphite.
Смесь из 0,1 г моль треххлористого фосфора , 0,3 г моль 2,4-лихлорфенола и 0,3 г ииридина нагревают в течение 2-3 час до 140- и выдерживают при этой температуре до прекращени выделени хлористого водорода (2-3 час). Получают практически чистый продукт (выход 100%), который почти целиком перегон етс при 245-250 С /1 мм/, т. ил. 37-39°С.A mixture of 0.1 g mol of phosphorus trichloride, 0.3 g mol of 2,4-lichlorophenol and 0.3 g of iiridine is heated to 140 for 2-3 hours and kept at this temperature until the evolution of hydrogen chloride stops (2-3 hour). A practically pure product is obtained (yield 100%), which is almost completely distilled at 245-250 C / 1 mm /, t. Il. 37-39 ° C.

Подобный результат получен при использовании в качестве катализатора хннолина (2 моль).A similar result was obtained when using hnnoline (2 mol) as a catalyst.
Когда катализатором был хлористый магний (2 моль. %), дл завершени реакции потребовалось нагревание при 160-170С в течение 4 час. Без катализатора реакци не доходит ко конца даже при нагревании до 190- .When the catalyst was magnesium chloride (2 mol.%), Heating at 160-170 ° C was required to complete the reaction for 4 hours. Without a catalyst, the reaction does not reach the end, even when heated to 190-.
Пример 2. Три-(2,4-дп-вгор-бутилфенил)фосфит .Example 2. Three- (2,4-dp-bu-butylphenyl) phosphite.
Пол}чен в услови х синтеза три-(2,4-дихлорфенил ) фосфита при использовании в качестве катализатора пиридина (2 моль. %).It is used under the conditions of synthesis of tri- (2,4-dichlorophenyl) phosphite using pyridine (2 mol.%) As a catalyst.
