Dispersion Resin for Polyvinyl Chloride). Marvinol VR-50, an allpurpose stir-in paste grade resin for high-shear plastisol and organosol uses is described in a 20-pagc booklet, in cluding formulation and compounding techniques. Bull. 12-500. Dept. IEC, Naugatuck Chemical Div., United States Rubber Co., Naugatuck, Conn. C-34
EQUIPMENT I W T engineers are frequently called on t o plan and build pilot plants and production e q u i p m e n t for applications of ionXchange to chemical processes. Interesting examples in clude recent installations for - •
Purification of citric acid, lactic acid, and t a r t a r i c acid by cation and anion exchange.
•
Removal of a l u m i n u m from phosphoric acid metal-finishing solutions,
•
Conversion of sodium ferroeyanidc to the a m m o n i u m form by cation ex change.
•
Removal of ash from beet sugar by continuous ion exclusion.
P R O C E S S E S
T h e I W T research laboratory is constantly engaged in evaluating exciting new processes such as ion exclusion, ion retardation, equilib rium separations, continuous moving-bed ionXchange, and others.
