Abstract

Procedeul de obtinere a metacrilatilor metalici conform inventiei consta în aceea ca se trateaza acidul metacrilic cu oxidul hidroxidul sau o sare a unui metal ales dintre calciu magneziu, aluminiu, cadmiu, în mediu apos, la temperaturi cuprinse între 25.....85 degree C, în prezenta eterului metilic al hidrochinonei ca inhibitor de polimerizare în concentratie de 600 ppm fata de acidul organic dupa care solventul apos se îndeparteaza prin evaporarea în atomizor la un debit al aerului de uscare de 300.....400 m la puterea3/h si la temperatura de intrare în atomizor de 145.....170 degree C, iar la iesire de 75.....90 degree C.The process for obtaining the metal methacrylates according to the invention consists in treating the methacrylic acid with the oxide hydroxide or a salt of a metal selected from magnesium, aluminum, cadmium in aqueous medium at temperatures of 25 ... 85 ° C C in the presence of hydroquinone methyl ether as a polymerization inhibitor at a concentration of 600 ppm relative to the organic acid after which the aqueous solvent is removed by evaporation in the atomizer at a drying air flow rate of 300 ... 400 m at the power 3 / h and at the inlet temperature of 145 ... 170 ° C and at 75 ... 90 ° C.
