SU558896A1 - The method of producing methyl chloride - Google Patents

Description

hydrogen chloride in the amount of 417 and 452 kg / h in a co-administration. The first layer contains 40 liters of catalyst 30 wt. % zinc chloride is not aluminosilicate, in the second layer - 74O l. At the exit of each layer, the temperature of the reaction gases of the CZ C is maintained by adjusting the temperature of the gases entering the co6g-1 branch layer. As the active catalyst decreases and the conversion of meganol. In the first layer, the temperature of the reaction gases at the inlet to the first and second layers is changed in a certain sequence (see Table 1).

Table 1

The yield of methyl chloride is 95.9%, the yield of dimethyl ether is 0.1%.

Example 2. Reagents Supplied in p &. the actor with three layers of the Cg talizator is the same as in Example 1. In order to stabilize

the yield of methyl chloride, as the activity of the catalyst of the reaction gases at the inlet to the first and last layer decreases, changes in a certain sequence (see Table 2).

In the third layer | the conversion is 96%, the yield of methyl chloride is 95.9%, the yield of Chshmethylether is 0.1%.
