Description
Предлагаетс способ количественного определени углерода и водорода в органических веществах ири помощи сожжени их в токе кислорода .A method is proposed for the quantitative determination of carbon and hydrogen in organic substances and by burning them in a stream of oxygen.
Известны методы аналитического сожжени органических веществ, где в качестве окислителей используют обычно окись меди или хромовокислый свинец.Methods of analytical burning of organic substances are known, where copper oxide or lead chromic acid is usually used as oxidizing agents.
Описываемый способ отличаетс от известных тем, что аналитическое сожл ;ение органических веществ производ т в присутствии окиси хрома.The described method differs from the known ones in that analytical compaction of organic substances is carried out in the presence of chromium oxide.
На чертеже схематически изображен прибор.The drawing shows a schematic of the device.
Прибор состоит из легкоплавкой стекл нной трубки 1 длиной 450-700 мм и диаметром 10-20 мм, заполненной измельченной до величины кусочков 1,5-2 мм, окисью хрома н поглотительных приборов: хлоркальциевой трубки 2 дл улавливанн воды, змеевиковых калнанпаратов 3 с окислительной смесью (раствор перманганата или хромпика в концентрированной серной кислоте) змеевикового калиаппарата 4 с раствором соли двухвалентного железа в 25-30%-ной серной кислоте, хлоркальциевой трубки 5 дл задерл :ани паров воды и стекл нных трубок 6, заполненных кусочклмн твердого едкого калн .The device consists of a fusible glass tube 1 with a length of 450-700 mm and a diameter of 10-20 mm, filled with chromium oxide crushed to a size of pieces of 1.5-2 mm and absorbing devices: a calcium chloride tube 2 for trapped water, coil kalnanparatov 3 with an oxidizing a mixture of (a solution of permanganate or chromic in concentrated sulfuric acid) of serpentine potassium 4 with a solution of ferrous iron salt in 25-30% sulfuric acid, calcium chloride tube 5 for dropping: anodized water vapor and glass tubes 6 filled with a piece of solid glass of sodium Calne.
При анализе веществ с большим содержанием азота число калиаппаратов с окислителем увеличивают до двух или даже трех. Если апализирземое вещество не содержит азота, то змеевиковые калиаппараты с окислителем или раствором соли железа станов тс излишними и их можно удалить.In the analysis of substances with a high content of nitrogen, the number of kaliappara with an oxidizing agent is increased to two or even three. If the apalized earth substance does not contain nitrogen, then serpentine kaliapparaty with an oxidizing agent or a solution of iron salt become superfluous and can be removed.
Через прибор пропзекают кислород и прокаливают трубку 1 в течение 10-20 мин., затем включают малую электропечь, отсоедин ют поглотительные приборы и перенос т в весовую комнату, где их взвешивают через 20 мин.Oxygen is passed through the device and the tube 1 is calcined for 10–20 min., Then a small electric furnace is turned on, the absorbing devices are disconnected and transferred to the weighing room, where they are weighed after 20 min.
Анализируемое вещество взвешивают в фарфоровой лодочке, засынают сверху сухой прокаленной окисью хрома, которую необходимоThe analyte is weighed in a porcelain boat, filled with dry, calcined chromium oxide, which is necessary
