(54) ЭЛЕКТРОХИМИЧЕСКИЙ СПОСОБ ПОЛУЧЕНИЯ ФОСФИТОВ(54) ELECTROCHEMICAL METHOD FOR OBTAINING PHOSPHITES
1one
Изобретение относитс к, технологии получени фосфитов.This invention relates to phosphite technology.
Известен электрохимический способ получени фосфитов путем окислени гипофосфитов на нлатиновом аноде.A known electrochemical process for the production of phosphites by the oxidation of hypophosphites at the nlatin anode.
Цель изобретени - повысить выход продукта .The purpose of the invention is to increase the yield of the product.
Дл этого окисление ведут в присутствии галоидоводородной кислоты, в качестве материала анода используют графит. (Вместо графита может быть иснользован уголь).For this, oxidation is carried out in the presence of hydrohalic acid, and graphite is used as the anode material. (Instead of graphite, coal can be used).
Предложенный способ обеспечивает почти количественное окисление гипофосфита в фосфит с выходом по току 60-65%.The proposed method provides almost quantitative oxidation of hypophosphite to phosphite with a current yield of 60-65%.
Раствор фосфита быть использован, например, дл приготовлени электролита дл химического никелировани . Кристаллический нродукт может быть выделен известными приемами , например выпариванием. Отгон юща с при этом галоидоводородна кислота может быть использована дл приготовлени свежей порции электролита.A phosphite solution to be used, for example, to prepare an electrolyte for chemical nickel plating. The crystalline product can be isolated by known methods, for example by evaporation. The halogen acid that is distilled off can be used to prepare a fresh portion of the electrolyte.
П р и М е р. В электролизер емкостью 135 мл заливают раствор, содержащий 2,2 г гипофосфита аммони и 6,15 г сол ной кислоты. Пропускают ток силой 1,8 а в течение 75 минPRI and MER. A solution containing 2.2 g of ammonium hypophosphite and 6.15 g of hydrochloric acid is poured into a 135 ml electrolyzer. Pass a current of 1.8 a for 75 minutes
(плотность тока 5 а/дм, электроды графитовые ), температура 35-40°С. Раствор после электролиза по анализу содержит 2,59 г фосфита аммони (КН4)2НРОз и 0,05 г фосфата аммони (NH4)2HPO4. Стенень превращени составл ет 98,3%, выход по току около(current density 5 a / dm, graphite electrodes), temperature 35-40 ° С. The analysis solution after electrolysis contains 2.59 g of ammonium phosphite (KH4) 2HPO and 0.05 g of ammonium phosphate (NH4) 2HPO4. The conversion wall is 98.3%, the current efficiency is about
63%.63%.
