Description

нием не осушаетс  и содержит около 0.026% воды.It does not dry out and contains about 0.026% water.

Применение стружки из хромоникелевой стали с присадкой серного колчедана позвол ет повысить удельную производительность колонны в 2-3 раза, при этом содержание ге-дибромбензола в жидких продуктах синтеза снижаетс  в 1,5-1,6 раза, а о-дибромбензола - в 1,9-2,0 раза, расход катализатора сокращаетс . Удельна  производительность аппарата составл ет 7-9 .The use of chromium-nickel steel chips with sulfur pyrite additive makes it possible to increase the specific productivity of the column by 2-3 times, while the content of hemi-dibromobenzene in liquid synthesis products decreases 1.5-1.6 times, and o-dibromobenzene - 1. 9-2.0 times, catalyst consumption is reduced. The specific productivity of the apparatus is 7-9.
