Description

Пример. В реактор, снабженный мешалкой , загружают 5 г нолихлоридов нафталина и 3(3 г Na S-OHiO. Реактор нагревают до расплавлени  сернистого натри , вк.тючают мешалку и испар ют кристаллизационную воду, постепенно повыша  температуру. При 150- 170°С начинаетс  реакци  взаимодействи  исходиых иродуктов, котора  заканчиваетс Example. 5 g of naphthalene nolichlorides and 3 (3 g of Na S-OHiO) are loaded into a reactor equipped with a stirrer. The reactor is heated to melt sodium sulphide, the mixer is evaporated and the water of crystallization evaporates, gradually raising the temperature interaction of the outgoing and products, which ends

бы€трым разогревом реакционной массы до 220-250°С и испарением остатка кристаллизационной воды. После этого содержимое реактора охлаждают, раствор ют в воде. Раствор отфильтровывают от непрореагировавшего остатка, а нафталинполитиолы выдел ют из раствора подкислением сол ной кислотой до полного их осаждени . После фильтрации , отмывки и сушки продукта получают 3,7 г нафталинполитиолов, что составл ет выход 78% от теоретического.if the heating of the reaction mass to 220-250 ° C and evaporation of the remainder of the water of crystallization. After that, the contents of the reactor are cooled, dissolved in water. The solution is filtered off from the unreacted residue, and the naphthalene polythiols are separated from the solution by acidification with hydrochloric acid until they are completely precipitated. After filtration, washing and drying of the product, 3.7 g of naphthalene polythiols are obtained, which accounts for 78% of the theoretical yield.
