Description

Элементарный анализ органических веществ и минерального - топлива в научно-нсследовательских институтах и лаборатори х производитс  в специальных трубчатых печах (электрических или обогреваемых газовыми горелками), причем трубки дл  сжигани  примен ютс  стекл нные (из тугоплавкого стекла), кварцевые и фарфоровые. Кварцевые трубки СЛИШКОМ дороги, а стекл нные трубки быстро выход т из стро  при работе и не позвол ют использовать весь интервал температуры, какую обычно дают печи, а тем самым очень замедл ют врем  анализа. Фарфоровые трубки при применении зерненой окиси меди (способ Либиха) не могут быть нагреты выше 600-700°, так как при перегреве они разрушаютс . Неосторожный нагрев электрической печи или местный перегрев газовой неизбежно вывод т ИЗ CTpoff фарфоровую трубку.Elementary analysis of organic matter and mineral - fuels in research institutes and laboratories is carried out in special tube furnaces (electric or heated by gas burners), with glass (of refractory glass), quartz and porcelain tubes used for burning. Quartz tubes are TOO expensive, and glass tubes quickly fail during operation and do not allow the use of the entire temperature range, which the furnaces usually give, and thus the analysis time is very slow. Porcelain tubes, when using granulated copper oxide (the Liebig method), cannot be heated above 600-700 ° C since they break down when overheated. Careless heating of the electric furnace or local overheating of the gas will inevitably remove the porcelain tube from the CTpoff.

Предлагаемый способ свободен от указанных недостатков и состоит в том, что дл  заполнени  нагреваемой трубки примен ют пропитанную раствором какой-либо соли меди или кобальта огнеупорную пористую массу в видеThe proposed method is free from the indicated drawbacks and consists in using a refractory porous mass impregnated with a solution of some copper or cobalt salt to fill the heated tube.

Известный в технике способ нанесени  катализатора на инертную массу применим и дл  реакции сжигани  органических соединений при элементарном анализе их. Огнеупорна  пориста  масса (фарфор, шамот и др.), пропитанна  азотнокислыми меди, кобальта и обожженна , представл ет собою неплавкий , имеюш,ий большую поверхность окислитель с достаточным запасом кислорода, который дает весьма хорошие результаты при элементарном анализе . Колбаски из медной сетки замен ютс  колбасками из никелевой сетки, так как окись никел  прочно держитс  на металле, причем пробка между сжигаемым вешеством и окислителем, по сути говор ,  вл етс  предохранительной от передачи огн  из нагретого пространства печи парам веш,ества; без такой предохранительной пробки возможны взрывы трубки, что и наблюдалось при попытках еще больше упростить снар жение трубки, дл  чего эта пробка не помещалась в трубку. Преимущества предлагаемого способа: 1) больша  точность анализа, так какThe method of applying a catalyst to an inert mass known in the art is also applicable to the combustion reaction of organic compounds in their elemental analysis. The refractory porous mass (porcelain, chamotte, etc.) impregnated with copper and cobalt nitrates and burned is a non-fusible, having a large oxidizer surface with an adequate supply of oxygen, which gives very good results in elementary analysis. Copper mesh sausages are replaced with nickel mesh sausages, since nickel oxide is firmly attached to the metal, and the cork between the burned substance and the oxidizer is, in essence, safe from transferring fire from the heated space to the steam oven; without such a safety plug, explosions of the tube are possible, which was observed when trying to further simplify the fit of the tube, for which this plug was not placed in the tube. The advantages of the proposed method: 1) greater accuracy of the analysis, since
