Description

Изобретение касаетс  способа получени  -феноксинигроалканов. Предлагаетс  способ получени  р,-фе- ноксинитроалканов взаимодействием фенола с оС-ннтроолефинами в присутствии катализатора - фенол та кали . Получен™ ные по предлагаемому способу -фенок синитроэтан и -фенокси-с.-нитропропан , представл ют интерес как промежуточные продукты при синтезе гербицидов и ростовых веществ. Пример, Синтез. 2-феноксиннтро- этана. В трехгорлую колбу, снабженную мешалкой и термометром, помещают 10 мол фенола и 1 моль свежеперегнанного нит- роэтилена. К смеси при комнатной температуре и хорошем перемешивании добавл ют О,О2 моль фенол та кали . Реакционную смесь выдерживают в течение 2О ч при температуре 2О-25 С, после чего ее раствор ют в эфире и нейтрали™ зуют концентрированной сол ной кислотой Выпавший при этом осадок отфильтровывают и эфир отгон ют. Оставшуюс  массу разгон ют под вакуумом. Вначале при 7О-9О С и 11 мм рт. сг. оггон юг фенол , а затем  ри температуре 114 С и 3 мм рТс ст. отгон ют продукт, который затвердевает в приемнике. Продукт имеет т, пл, 41,5 С, Выход продукта (в расчете на нитроэтилен) 51%. Найдено,%: С 57,25; 57,27; Н 5,51} 5,43; Мол.вес, 168,7. ВычисленоД: С 57,4| Н 5,91; ол.вес. 167,2, Аналогично из фенола и оС-иитропропи- ена получают р -фенокси-о -1штропропан выходом 67% и следующими физикоимическими свойствами: т. кип. 1,512О 2 мм рто cT,g  The invention relates to a process for the preparation of α-phenoxy nigroalkanes. A method is proposed for producing p, α-phenoxynitroalkanes by reacting phenol with oC n-n-olefins in the presence of a catalyst — phenol and potassium. Obtained by the proposed method, phenok cinitroethane and -phenoxy-c-nitropropane, are of interest as intermediates in the synthesis of herbicides and growth substances. Example, Synthesis. 2-phenoxynthroethane. In a three-necked flask equipped with a stirrer and a thermometer, 10 moles of phenol and 1 mole of freshly distilled nitroethylene are placed. To the mixture at room temperature and with good stirring, was added O, O2 mol of potassium phenol. The reaction mixture is kept at 2O-25 ° C for 2 hours, after which it is dissolved in ether and neutral ™ is concentrated with concentrated hydrochloric acid. The precipitated precipitate is filtered off and the ether is distilled off. The remaining mass is distilled under vacuum. Initially, at 7O-9O C and 11 mm Hg. cr. Oggon yug phenol, and then at a temperature of 114 ° C and 3 mm pTc Art. the product which solidifies in the receiver is distilled off. The product has t, mp, 41.5 C, the yield of the product (based on nitroethylene) is 51%. Found,%: C 57.25; 57.27; H 5.51} 5.43; Mol.ves, 168.7. Calculated D: C 57.4 | H 5.91; ol.ves. 167.2. Similarly, p -phenoxy-o-1stropropane with a yield of 67% and the following physicochemical properties are obtained from phenol and oC-iitropropylene: t. Bale. 1,512О 2 mm рто cT, g
