Description

Известен способ получени  фурфурола из растительных сельскохоз йственных отходов нутем их гидролиза и последующей дегидратации пентоз.A known method for the production of furfural from plant agricultural wastes by chipping their hydrolysis and subsequent dehydration of pentoses.

Недостатком этого способа  вл етс  невысокий выход продукта. Описываемый способ повышает выход фурфурола и исключает разрушение целлюлозы, что достигают проведением процесса дегидратации пентоз в разбавленном растворе, папример, при концентрации их около 10%. Такой способ получени  фурфурола дает возможность осуществить схему комплексной переработки растительных сельскохоз йственных отходов (в частности, хлопковой шелухи) па спирт и фурфурол с выходами не ниже, чем получаемыми при раздельной переработке этого сырь  либо на фурфурол, либо на спирт.The disadvantage of this method is the low yield of the product. The described method increases the yield of furfural and eliminates the destruction of cellulose, which is achieved by carrying out the process of dehydration of pentoses in a dilute solution, for example, at a concentration of about 10%. This method of obtaining furfural makes it possible to carry out a scheme for the complex processing of vegetable agricultural wastes (in particular, cotton husks) on alcohol and furfural with yields not lower than those obtained by separately processing this raw material either on furfural or on alcohol.

Предмет изобретени Subject invention

Способ получени  фурфурола из растительных сельскохоз йственных отходов путем их гидролиза и последующей дегидратации пентоз, отличающийс  тем, что, с целью повышени  превращени  пентоз в фурфурол и устранени  разрушени  целлюлозы, процесс дегидратации пентоз ведут в разбавлеппом растворе, например, при концентрации их около 10%.The method of obtaining furfural from plant agricultural wastes by their hydrolysis and subsequent dehydration of pentoses, characterized in that, in order to increase the conversion of pentoses to furfural and eliminate the destruction of cellulose, the process of dehydrating pentoses is carried out in a dilute solution, for example, at a concentration of about 10%.
