Description

ке водорода 2 ч, затем реактор ОХлаждают и выгружают 45 г кокса.hydrogen for 2 h, then the OX reactor is cooled and 45 g of coke are discharged.

Затем 550 г размолотого кокса, полученного по приведенному выше способу, загружают в реактор, подают 750 г жидкого фтористого водорода п ввод т фтор в течение 50 ч при 17°С до образовани в реактО|ре давлени 2 ати. Введенное количество фтора составл ет 430 л. Получают 1100 г монофторида углерода с отношелием С : ,2 : 1.Then, 550 g of milled coke obtained by the above method are loaded into the reactor, 750 g of liquid hydrogen fluoride are fed and fluorine is introduced during 50 hours at 17 ° C until a pressure of 2 bar is formed in the reactor. The amount of fluorine added is 430 liters. 1100 g of carbon monofluoride are obtained with a ratio of C: 2: 1.

Пример i2. 500 г кокса разгружают в реактор с мешалкой и подают 750 г жидкого фтористого водорода. Смесь перемешивают посто нно в течение 30 ч .при 20°С с одновременной подачей фтора до давлени 2 ати в количестве 520 л. Получают 1250 г монофторида углерода ;с отношением С : Р 0,98: 1.Example i2. 500 g of coke are discharged into the stirred reactor and 750 g of liquid hydrogen fluoride are fed. The mixture is stirred continuously for 30 hours at 20 ° C with simultaneous supply of fluorine to a pressure of 2 bar in an amount of 520 l. 1250 g of carbon monofluoride are obtained, with a C: P ratio of 0.98: 1.

П|ри1мер 3. 500 г -кокса загружают в реактор . Подают 500 г фтористого водорода. Реактор помешают в термостат при 0°С. Подают в течение 30 ч 550 л фтора до давлени 2 ати. Получают 1310 г серо-белого порошка с содержанием фтора 61,4 вес. %.P | ri1mer 3. 500 g of coke is loaded into the reactor. Served 500 g of hydrogen fluoride. The reactor is placed in a thermostat at 0 ° C. For 30 hours, 550 liters of fluorine are supplied to a pressure of 2 MPa. Receive 1310 g of a gray-white powder with a fluorine content of 61.4 wt. %

Claims

The invention claims 1. A method for producing carbon monofluoride and by treating carbon with fluorine-containing gas (a product distinguished by the fact that, in order to ensure the possibility of carrying out the process under normal conditions, petroleum pitch is heated in an atmosphere of hydrogen at 700-800 ° C and the treatment with fluorine is carried out in the presence of liquid hydrogen fluoride.

2. The method according to claim 1, from l and h ayo and yc in that the weight ratio of hydrogen fluoride to the carbon-containing product and fluorine is 0.5: 1: 0.6-1: 1: 1.6.
