PRI me R. 97 g of furfurylamine and a solution of 138 g of carbonic acid in i, 4 l of water are placed in a glass vessel with a stirrer, a repMONieTpoM and a water bath.

To the resulting solution, while stirring the stirrer and cooling in a water bath, 516 g of methyl sulfate (SLR) is added dropwise to the solution (maintaining the internal temperature of m: s 20-25 °. Then incubated for 1 hour while stirring and room temperature, increase the temperature up to 50 ° C and again allowed to stand for i -1.5 hours. Freely. The amines from the reaction mixture are distilled off with steam: to neutralize 11 per litmus of the condensate reaction, so that the reaction1 Bi yTpit mass is stable in alkaline; on litmus.

The dry residue (600 s-) is crushed over a mortar and recrystallized from 1 l of alcohol with butyl acetate, taking g: - ;: 1: 4, when fuming a hot water bath. 1 op chi :: raetsor is sucked off from the salt 11 (potassium sulfate sulphate), after which the biezolsulfonate trimethyl furfurfurylamyl lune is crystallized from the filtrate while cooling.

The yield of the product is 148-150 s or 50% of the theoretically possible amount, calculated on the initial furfurylamine.

Bepzolsulfonate trimethylfurfuryl.monium is a solid, religious, white pvet, with a specific odor and temperature 133-IS-f. On it is highly soluble in water and alcohol and insoluble in ethyl alcohol and esters. It is stable when stored in air, pegygroscopic.

PRIORITY

The method of producing ammonium nitrate sulfonate and ammonium nitrate, ammonium sulfate, and the fact that furfurilamic in an aqueous solution of potassium carbonate is treated with benzylsulfonate methyl ether, and the benzene sulfrometephteptrateff is removed from the reaction mass after purification and drying produced by known methods. .
