Abstract:
The water dissolved scale inhibitor containing sulfonic acid group is synthesized from the monomers of acrylic acid (AA) and sodium 1- allyloxy- 2- hydroxypropl sulfonate ( COPS- 1) , by water as solvent and sodium hypophosphite- sodium persulfate as initiators. In four-mouth flask holding mechanical stirrer, refluxcondenser, isoprestic- ipressure- funnel and thermometer, sodium hypophosphite, a litt le auxiliary and water are added in definite proport ion. In fixed temperature and stirring conditions, sodium persulfate solution and COPS- 1/AA mixing solution are added by drop at the same time. With experimental optimization, the effects of the monomer. s ratio, the amount of initiator, reaction temperature and reaction t ime, corresponding to the copolymer scale inhibiting performance are studied. The opt imum synthesis technique condition is obtained. The results show that the copolymer has obvious scale inhibit ing and dispersing performance.
