Description
По способу, описанному в основном изобретении дл приготовлени сернистого красител защитного цвета, нагревают с серой и сернистым натром нейтрализованный продукт сульфировани сольвентнафты.According to the method described in the basic invention for the preparation of a protective sulphurous dye, the neutralized sulfonation product of solvent naphtha is heated with sulfur and sulphurous soda.
Дальнейшие изыскани в этой области показали изобретател м, что дл реакции сульфировани в цел х последующего получени сернистого, не выцветающего на свету, красител защитного цвета может быть вз та также карболова кислота и что существенным моментом в дальнейшей обработке продукта сульфировани , как и в основном изобретении, вл етс нейтрализаци продукта известью, причем известь играет роль катализатора. Весь процесс приготовлени краски остаетс тот же, что и в основном способе.Further research in this area showed the inventors that for the sulfonation reaction, for the subsequent preparation of a sulfurous, non-fading light, a dye of a protective color can also be taken with carbolic acid and that the essential point in the further processing of the sulfonation product as in the basic invention Is neutralizing the product with lime, and lime plays the role of a catalyst. The entire paint preparation process remains the same as in the basic process.
По мнению изобретателей, нейтрализаци продуктов сульфировани содой или едким натром или пр мо сернистым натром не может дать краски ни тойAccording to the inventors, neutralizing sulfonation products with soda or caustic soda or directly sulphurous soda cannot give paint to any
крепости, ни того оттенка, как нейтрализаци известью, котора , вход в сплав в виде сульфосоли, действует как катализатор .strength, neither of which is neutralized by lime, which, as an entrance to the alloy in the form of sulfosal, acts as a catalyst.
Пример: Три пуда карболовой кислоты смешивают с шестью пудами купоросного масла и нагревают до 80 градусов. По окончании реакции разбавл ют водой и нейтрализуют известковым молоком до слабо-щелочной реакции . Отфильтровав от гипса, фильтрат упаривают до небольшого объема, прибавл ют к нему шесть пудов сернистого натри и три пуда серы, выпаривают до суха и прокаливают в течение восьми часов при 250 - 300° С.Example: Three pounds of carbolic acid are mixed with six pounds of vitriol oil and heated to 80 degrees. At the end of the reaction, it is diluted with water and neutralized with lime milk until slightly alkaline. After filtering off the gypsum, the filtrate is evaporated to a small volume, six tons of sodium sulphide and three pounds of sulfur are added to it, evaporated to dryness and calcined at 250-300 ° C for eight hours.
ПРЕДМЕТ ИЗОБРЕТЕНИЯ.SUBJECT OF INVENTION.
Видоизменение способа, описанного в патенте № 63, отличающеес тем, что вместо нейтрализованного продукта сульфировани сольвентнафты примен етс нейтрализованный известью продукт сульфировани карболовой кислоты.A modification of the method described in Patent No. 63, characterized in that instead of the neutralized sulfonation product of solvent naphtha, the lime-neutralized sulfonation product of carbolic acid is used.
