Description
Получение фурфурола действием перегретого пара на смоченные кислотой содержащие пентозаны материала давало обычно довольно невысокие выхода фурфурола.The production of furfural by the action of superheated steam on the material containing pentosans moistened with acid usually gave rather low yields of furfural.
Автором найдено, что выхода фурфурола могут быть значительно повышены при применении аппарата специальной конструкции, в котором пар впускают в аппарат сверху и содержащие фурфурол пары вывод т снизу аппарата, чем обеспечиваетс быстрое удаление т желых паров фурфурола и повышение выходов фурфурола.The author has found that the yields of furfural can be significantly increased by using an apparatus of special design in which steam is admitted into the apparatus from above and fufural containing fumes are drawn from the bottom of the apparatus, thus ensuring rapid removal of heavy furfural yields and increasing furfural yields.
Предлагаемый аппарат (см. чертеж) представл ет собою вepтикaльч зIЙ цилиндрический котел, снабженный паровой рубашкой /. Дл впуска пара служит патрубок 2. Дл выпуска пара с фурфуролом применена труба 3, открыта снизу и опущенна до дна аппарата.The proposed apparatus (see drawing) is a vertical cylinder cylindrical boiler fitted with a steam jacket. Pipe 2 serves as a steam inlet. Pipe 3 is used to release steam with furfurol, is open at the bottom and lowered to the bottom of the apparatus.
В аппарате такой конструкции из кукурузной кочерыжки, смоченной 6%In the apparatus of this design of corn stalk moistened with 6%
от веса кочерыжки сол ной кислоты, разбавленной примерно 10%-м количеством воды, при температуре пара, поступающего в аппарат, в 100-130°, и пара, поступающего в рубашку, в 200- 206° (пар, в обоих случа х перегретый атмосферой давлени ), получено фурфурола 12,6% и кислот 0,5% от веса кочерыжки.of the weight of the stalk of hydrochloric acid, diluted with approximately 10% of water, at a temperature of steam entering the apparatus, 100-130 °, and steam entering the jacket, 200-206 ° (steam, in both cases, overheated pressure atmosphere), obtained furfural 12.6% and acid 0.5% by weight of the stalk.
Предмет изобретени .The subject matter of the invention.
Аппарат дл получени фурфурола действием перегретого пара при атмосферном давлении на смоченные кислотой пентозан содержащие материалы, отличающийс тем, что, с целью осуществлени движени паров в аппарате сверху вниз, патрубок дл выпуска пара расположен в верхней части аппарата, а дл выпуска устроена открыта снизу труба, опущенна почти до дна аппарата .An apparatus for obtaining furfural by the action of superheated steam at atmospheric pressure on acid-moistened pentosan containing materials, characterized in that, in order to move the vapor in the apparatus from top to bottom, a branch pipe for steam release is located in the upper part of the apparatus, lowered almost to the bottom of the apparatus.
