Description
Прпме:р 2. В услови х примера 1 в реактор загружают 0,2 мол лг-толунитрила, уксусную кислоту и катализатор. Услови процесса: температура 100°С, расход кислорода 400 л/ч на 1 моль л-г-толунитрила, исходна Example: p 2. Under the conditions of Example 1, 0.2 mol of L-tolunitrile, acetic acid and a catalyst are charged to the reactor. Process conditions: temperature 100 ° C, oxygen consumption 400 l / h per 1 mol lg-tolunitrile, initial
%. копцеитради льтолунитрила 30 вес.% Kotseitradi ltolunitrila 30 wt.
Состав катализатора, 1 моль на 1 моль -Ктолунитрила: бензоат кобальта 0,0065, бензоат марганца 0,0005, бромистый аммоний 0,006. За врем реакции (2 ч) выход лг-цианбензойной кислоты составл ет 65 мол.% на вз тый и 100% на прореагировавший льтолуиитрил . Методика выделени уи-цианбензойной кислоты така же, как в примере 1. Т. ил. полученной лг-цианбепзойной кислоты 217°С.The composition of the catalyst, 1 mol per 1 mol -Ctolunitrile: cobalt benzoate 0.0065, manganese benzoate 0.0005, ammonium bromide 0.006. During the reaction (2 hours), the yield of lg cyanbenzoic acid is 65 mol.% For the taken and 100% for the reacted ltoluiitrile. The procedure for the isolation of ui-cyanbenzoic acid is the same as in Example 1. T. Il. the obtained lg cyanbepsoic acid 217 ° C.
Пример 3. В услови .х примера 1 в реактор загрул ают 0,2 мол 3,5-диметилбензонитрила , уксусную кислоту и катализатор. Услови процесса: температура 95°С, расход кислорода 300 л/ч на 1 моль диметилбензонитрила , исходна концентраци диметилбензоннтрила 30,0 вес. %.Example 3. Under the conditions of example 1, 0.2 mol of 3,5-dimethylbenzonitrile, acetic acid and catalyst were charged to the reactor. Process conditions: temperature 95 ° C, oxygen consumption 300 l / h per 1 mol of dimethylbenzonitrile, initial concentration of dimethylbenzonntrile 30.0 weight. %
Состав катализатора, 1 моль на 1 моль диметилбензонитрила: беизоат кобальта 0,007,The composition of the catalyst, 1 mol per 1 mol of dimethylbenzonitrile: cobalt beisoate 0,007,
бензоат марганца 0,005, бромистый аммоний 0,006. За врем реакции (3 ч) выход цианбензойной кислоты составл ет 50% на вз тый и 100% на ирореагировавший диметидбензонитрил . Ползченную кислоту выдел ют таким же способом, как в примерах 1 и 2.manganese benzoate 0.005, ammonium bromide 0.006. During the reaction (3 hours), the yield of cyanobenzoic acid is 50% for the taken and 100% for the unreacted dimetibenzonitrile. Crawled acid is isolated in the same manner as in Examples 1 and 2.
