Method of producing mesoporous carbon material activated with potassium hydroxide, in particular for isolating di-n butyl phthalate, butyl benzyl phthalate and di(2-ethylhexyl) phthalate by solid phase extraction

摘要

The purpose of the notification is the production of mesoposed potassium-activated hydrocarbon material used as sorbent in the column for the isolation of dimethyl phthalate and diethyl phthalate by the solid phase extraction method, in reaction to the co-polymerisation of 7,5 parts of the hydraulic weights of Pluronic F127 and 7, 5.Weight fractions of resorcinol and 8.2. Weight fractions of formaldehyde with concentration 36% -38% of weight, and after separation from the reaction mixture of the copolymer after heating for 24-hours. at temperature 100,C is carbonised in the nitrogen atmosphere (flow 20,dm3/h) at temperature 180,C for five hours and at temperature 850,C for two hours,and then three parts of the weight of the carbonised preparation are mixed with nine parts of the weight of KOH and the mixture is heated in the nitrogen atmosphere (flow of gas 20 dm3/h) at temperature 700oC for two hours consists of adding to one part the weight of the mesoposed carbon ten parts of the weight 0,1 M solution HCl and mixing the whole in the ultrasonic field 25kHz, and then after separation of this acid, ten parts of the weighing water shall be added to the 1-part of the mesoported carbon material and the whole shall be mixed in the ultrasonic field 25kHz.
