Abstract
Способ отгонки растворителя (этилацетата) из пороховых элементов сферического пороха, включающий подачу теплоносителя в рубашку аппарата с температурой 85°C и последующим нагревом теплоносителя на 1°C через 10 мин до температуры 98°C и в последующем на 2°C через 10 мин до температуры 98…100°C, после чего делается выдержка в течение 30…35 мин, отличающийся тем, что отгонку растворителя из пороховых элементов сферического пороха ведут по температуре теплоносителя, подаваемого в рубашку реактора, где подъем температуры с 68 до 86…87°C осуществляют в течение 10…15 мин и ведут процесс отгонки растворителя из пороховых элементов за счет разности парциальных давлений между реактором и холодильником при постоянной температуре 86…87°C, при этом отгоняют 70…75 мас.% растворителя от общего количества, затем в течение 10…15 мин поднимают температуру теплоносителя до 98…100°C и отгоняют оставшуюся часть растворителя. The method of distillation of the solvent (ethyl acetate) from the powder elements of spherical powder, comprising supplying a coolant to the jacket of the apparatus with a temperature of 85 ° C and then heating the coolant at 1 ° C after 10 min to 98 ° C and then at 2 ° C after 10 min to temperature 98 ... 100 ° C, after which exposure is done for 30 ... 35 minutes, characterized in that the solvent is removed from the powder elements of spherical powder by the temperature of the coolant supplied to the reactor jacket, where the temperature rises from 68 to 86 ... 87 ° C carried out in flow 10–15 min and the process of distillation of the solvent from the powder elements is carried out due to the partial pressure difference between the reactor and the refrigerator at a constant temperature of 86 ... 87 ° C, while 70 ... 75 wt.% of the solvent is distilled from the total amount, then for 10 ... 15 minutes raise the temperature of the coolant to 98 ... 100 ° C and drive off the rest of the solvent.
