Description
(54) СПОСОБ ПОЛУЧЕНИЯ ХЛОРИДА ХРОМА(54) METHOD FOR PRODUCING CHROMIUM CHLORIDE
хрома (VI) до хлорида хрома (б-водного) идет по реакции.chromium (VI) to chromium chloride (b-water) is the reaction.

Реакци идет согласно стехиометрии уравнени , об этом суд т цо количеству поглощенного водорода (68 мл) и резкому смещению величины потенциала раствора на 0,5 в в катодную область, что соответствует количественному превращению хрома (VI) в хром (1П). После отделени платиновой черн фильтрованием, упаривани раствора и кристаллизации хлорида хрома (6-водного) выход продукта составл ет 0,53 г, то есть 100% от теоретического.The reaction proceeds according to the stoichiometry of the equation, this is judged on the amount of absorbed hydrogen (68 ml) and a sharp shift of the solution potential by 0.5 V to the cathode region, which corresponds to the quantitative conversion of chromium (VI) to chromium (1P). After separation of the platinum black by filtration, evaporation of the solution and crystallization of chromium chloride (6-aqueous), the product yield is 0.53 g, i.e. 100% of the theoretical.
Образующийс продукт темно-зеленого цвета; аналитически показано, что содержание основного вещества - хлорида хрома 98% и продукт удовлетвор ет ГОСТу 4473-69 (квалификаци «ч. д. а.).The resulting product is a dark green color; It is analytically shown that the content of the main substance, chromium chloride, is 98% and the product satisfies GOST 4473-69 (qualification “h. d. a.).
