Text
This invention relates to a method of dehydrate barium hydroxide hydrates.
本发明是有关水合氢氧化钡脱水的方法。
Barium hydroxide octahydrate, monohydrate, and anhydrous barium hydroxide are known as well pounds.
八水合,一水合及无水氢氧化钡都是定义明确的化合物。
Text
Products having varying contents water of crystallization between the mono- and the octahydrate are also industrially used.
结晶水含量在一到八之间的氢氧化钡也是工业上常用的。
八水合氢氧化钡同成份熔融于其结晶水中。
Barium hydroxide octahydrate congruently melts in its own water of crystallization.
Text
The water cannot be removed from this solution otherwise than by prolonged heating at temperatures up to 300℃.
这些水只有通过长时间的在300℃以上加热才能从溶液中除去。
The process is panied by troublesome spattering and incrustation phenomena.
这个工艺伴随着讨厌的飞溅和结壳现象。
Text
An improvement can be achieved by dehydrating under reduced pressure at a temperature of about 130 ℃.
对该方法的改进措施是在大约130℃时减压条件下脱水。
The barium hydroxide octahydrate will then, when slowly heated, lose part of its water of crystallization at temperature below its congruent melting point of 78℃, so that the solid state is preserved throughout the dehydrating process.
当缓慢加热时,八水合氢氧化钡将在温度低于其同成份熔点即78℃时失去部分结晶水,从而在整
