(54) СПОСОБ ПОЛУЧЕНИЯ ГИДРАТОВ ПЕРЕКИСЕЙ ПИНАНА И п-МЕНТАНА(54) METHOD FOR OBTAINING PINAN AND PERC MENTANE HYDRATES
Выход смеси пишна и п-ментана до 80-90%. Другие углеводороды, вход щие в состав продуктов гидрировани , практически не образуют при окислешш пцфатов перекисей и вл ютс только инертными разбавител ми.The output of the mixture of clerical and p-menthane to 80-90%. The other hydrocarbons in the composition of the hydrogenation products, practically do not form during oxidation of PCP peroxides and are only inert diluents.
П р и м е р 1. В осадитель ввод т 0,5 м водного раствора нитрата никел (100 г/л никел ), 25 кг каолина и 25 кг кремнезема, добавл ют растъор гидроокиси натри (200 г/л), отдел ют осадок на фильтрпрессе, отмывают от нитрат-ионов, сушат и таблетируют. Полученный катализатор восстанавтваюгг при 400 С в течение 8 час, подава 600 объемов водорода на 1 объем катализатора за 1 час. Сульфатный скипидар (свыше 60% изомеров цимола ) гидрируют на катализаторе при 140° С, расходу m 1 л катализатсча 300 л/час водорода и 0,4 час скипидара. Получают продукт, содержащий 54,6% гьментава, 37,5% пинана и 0,8% изомеров цимола. 250 г полученного продукта окисл ют кислородом воздуха при 115° С до образовани 20% гидратов перекисей. Врем окислени 6 час. При перегонке с вод ным паром в вакууме (10-80 мм рт.ст.) отгон ют непрореапфовавитй скипидар и получают продукт, содержащий 52% гидратов перекисей.Example 1: 0.5 m of an aqueous solution of nickel nitrate (100 g / l nickel), 25 kg of kaolin and 25 kg of silica are added to the precipitant, a solution of sodium hydroxide (200 g / l) is added, sediment on filter press, washed from nitrate ions, dried and tableted. The resulting catalyst was reduced at 400 ° C. for 8 hours, feeding 600 volumes of hydrogen to 1 volume of catalyst in 1 hour. Sulfate turpentine (over 60% of isomers of zimol) is hydrogenated on a catalyst at 140 ° C, consumption of m 1 l of catalytic acid is 300 l / h of hydrogen and 0.4 hour of turpentine. A product is obtained containing 54.6% gjmentava, 37.5% pinan and 0.8% zymol isomers. 250 g of the product obtained is oxidized with oxygen at 115 ° C to form 20% of peroxide hydrates. The oxidation time is 6 hours. By distillation with water vapor in vacuum (10-80 mm Hg), unreacted turpentine is distilled off and a product containing 52% of peroxide hydrates is obtained.
П р м е р 2. На катализаторе, приготовленном, как в 1фим6ре 1, прн 150° С гндр1фуют диспропорционированный скипидар, вл ющийс побочньп«( продуктом при производстве канифольного мыла и содержащий 33,5% п-цимола, 6,4% м-щшола, Ili2%EXAMPLE 2: A catalyst prepared as in 1Fim 1, 150 ° C, contains disproportionate turpentine, which is byproduct (a product used in the production of rosin soap and containing 33.5% p-cymol, 6.4% m -shchola, Ili2%

Продукты гидрировани содержат 30,9% пинана, 51,2% п-ментана, 0,6% изомеров цимола, 0,2% а- и пиненов и 0,1%EXAMPLE 3 On the same catalyst as in example 1, in the conditions of example 2, ssstractional turpentine is hydrogenated. containing 52.8% a-and pinenov and 32.6% D - Caren. Hydrogenation products contain 30.9% pinane, 51.2% p-menthane, 0.6% cymol isomers, 0.2% a- and pinenes, and 0.1%
