アセチレンガスに対する液体清浄剤に関する研究(第1報)

抄録

Acetylene always contains, more or less hydrogen sulphide, phosphine when produced from a generator.
It is obvious that the employment of non-purified gas in welding presents many faults.
Granjon, Booer, and Leeds employed ferric chloride to fix impurities. Acetylene in contact with a reactive material containing ferric chloride and ferric oxide removes hydrogen sulphide, phosphine.
This reactive materials (powdered purifying materials) which can be repeated until the product has become inactive, have been used widely.
But, the velocity of the gas passed through a purifier is retarded by wet acetylene and purifying power will become less, therefore it is essential to throughly remove the moisture prior to pass.
Liquid purifiers have had to be abanded nearly because their power is relatively weak.
Nevertheless, we know that liquid purifier is more convenient and gas is bubbled through a solution.
So that, it is necessary to find a superior liquid purifier.
This report has two main objects : to clear the purifying power of ferric chloride and cupric chloride which used principally for powdered purifier, and to determine the effect of stannic chloride on these solutions.
Laboratory equipment employed for removal of impurities from acetylene consists in passing bubbles and verification of gas purified.
At a bottom of cylindrical vessel, the bubbles are made to pass through a nozzle into a solution.
Verification of gas purified is done by Kitagawa's phosphine detecting tube.
