Description
Изобретение касаетс способа непрерывного получени щавелевокислого наггри путем нагрева формиата «атри до 360-400° в Присутствии паров во)ды.The invention relates to a process for the continuous production of oxalate nagrig by heating formate "atri to 360-400 ° in the Presence of vapors in the vapor."
Автором насто щего и|зобретени установлено, что, пользу сь насыщен .ньш оводвым раствором форйлиата натри (концентрацией до , при 80°) вмесТо обычно приме емхэго расплавленного формиата натри , можно совершенно устра1нить взрывы в производсФве оксалата натри . Так как при подаче водного раствора формиата натри во вращающуюс электропечь бараба1нного типа при: 360-400° получаетс на поверхности электропечи. тонкий слой оксалата натри , который непрерывно снИ1маетс раклей, а испар юща с при этом вода образует пар, вл ющийс инертной сре;дой, исключающей возможность взрыва вод орода в момейт его выделени .The author of this invention has found that by using saturated sodium sulfate solution (concentration up to, at 80 ° C) with an aqueous solution of sodium forylate (concentration up to 80 °), usually taken together with molten sodium formate, explosions in the production of sodium oxalate can be completely eliminated. As with the supply of an aqueous solution of sodium formate into a rotating electric furnace of the drum type with: 360-400 ° is obtained on the surface of the electric furnace. a thin layer of sodium oxalate, which is continuously removed with a scraper, and the evaporating water forms steam, which is an inert medium, making it impossible for the water to explode during its release.
Предмет изобретени .The subject matter of the invention.
Спо:соб непрерывного получени ща1велевокислого натри нагревом формиата натри до 360-400° в при сутствии паров воды, отличающийс тем, что формиат натри подают па плавку в виде насыщенного водного раствора.A method of continuous production of sodium bicarbonate by heating sodium formate to 360-400 ° in the presence of water vapor, characterized in that sodium formate is fed to the melt in the form of a saturated aqueous solution.
