Abstract: The invention concerns a phosphoric acid ester of Formula (I) or (II), wherein: A, B and R represents an aliphatic, cycloaliphatic and/ or aromatic moiety; Q represents —CH2—, —O— or —COO—; n+m is inferior to 3; and X+Y is less than 7, and wherein the phosphoric acid ester has an average molecular weight Mn of 70 to 10,000 g/mol. The invention also concern the process for making the phosphoric acid ester of Formula (I) or (II), and there us as dispersants of particles in a liquid medium, such as water, solvent, plasticizer or resin. Advantageously, the process allows the preparation of new high performing polymeric phosphate esters with less acidic character that are majorly a phosphate diester. Also, a 100% active liquid solvent free polyester phosphate ester can be effectively prepared.
Abstract: The present invention relates to light color, shelf-stable liquid compositions of overbased calcium carboxylate soaps and a process for their preparation. The inventive soaps are prepared by neutralizing calcium base in a mixture of two different aliphatic carboxylic acids and carbonating the mixture in the presence of a non-polar hydrocarbon solvent and a polar organic solvent as a promoter under controlled temperature conditions. The overbased calcium carboxylate soaps of the invention contain 20%-90% by weight of C7 to C25 saturated carboxylic acids, which are branched on carbon 2, and between 1% and 20% by weight short chain saturated carboxylic acids. These liquid compositions have light colors and excellent heat stability. They can be used as anticorrosion/antirust additives, and paint dryers and stabilizers, in paints, coatings and lubricants, as well as other applications.
