Пример J..L означает 1,8-нафтоилен- 1 , 2 -бензимидазол.Example J..L means 1,8-naphthoylene-1, 2-benzimidazole.
Получение молекул рного комплекса хлорида цинка с 1,8-нафтоилен-1 , 2-бензимидазолом ( 2 н СВ 2Ь ) .Preparation of the molecular complex of zinc chloride with 1,8-naphthoylen-1, 2-benzimidazole (2 n CB 2b).
В трехгорлой колбе, снабженной обратным холодильником, мешалкой и капельной воронкой раствор ют при кип чении Ь,4 г (0,02 моль) 1,8--нафтоилен-1 , 2 -бензимидазола в 200 мл тщательно очищенного бензола. К полученному раствору по капл м прибавл , ют 1,36 г (0,01 моль) безводного хлорида цинка, растворенного в 25 мл этанола. Реакционную смесь кип т т 20 мин, охлаждают до комнатной температуры , при которой выпадают кристаллы комплексного соединени . Осадок комплекса лимонно-желтого цвета отфильтровывают на фильтре Шота № 3, трижды промывают гор чей бензольноспиртовой смесью (3;1) и сушат в вакуум-сушильном шкафу при 150°С и 20 мм рт,ст,In a three-necked flask equipped with a reflux condenser, a stirrer and an addition funnel are dissolved at reflux, 4 g (0.02 mol) of 1.8-naphthoylen-1, 2-benzimidazole in 200 ml of thoroughly purified benzene. 1.36 g (0.01 mol) of anhydrous zinc chloride dissolved in 25 ml of ethanol was added dropwise to the solution obtained. The reaction mixture is boiled for 20 minutes, cooled to room temperature, at which crystals of the complex compound precipitate. The precipitate of the complex of a lemon-yellow color is filtered on Shot No. 3 filter, washed three times with a hot benzene-alcohol mixture (3; 1) and dried in a vacuum oven at 150 ° С and 20 mm Hg, st,
