标 题:Process for the synthesis of phenyl esters
发明人:LOWRANCE W
权利人:EASTMAN KODAK CO
摘要:A PROCESS FOR THE SYNTHESIS OF PHENYL ESTERS DIRECTLY FROM THE CORRESPONDING PHENOLS AND CARBOXYLIC ACIDS WHICH COMPRISES CONTACTING A PHENOLIC COMPOUND HAVING AT LEAST ONE HYDROGEN ATOM ADJACENT THE ACTIVE HYDROXYL GROUP WITH A CARBOXYLIC ACID COMPOUND CONTAINING AT LEAST ONE ACTIVE CARBOXYLIC GROUP IN THE PRESENCE OF A CATALYTIC AMOUNT OF A BORATE-SULFURIC ACID CATALYST COMPLEX. THE PROCESS IS CARRIED OUT IN A SINGLE STAGE REACTOR WHICH MAY BE OPERATED AT FROM 75*C. TO 285*C. UNDER ATMOSPHERIC, SUBATMOSPHERIC OR SUPERATMOSPHERIC PRESSURE. IF DESIRABLE, A SOLVENT CAN BE EMPLOYED.

标题:Anionic polymers composed of dicarboxylic acids and uses thereof
发明人:SANDERS JOHN LARRY; MAZO GRIGORY; MAZO JACOB
摘要:Biodegradable anionic polymers are disclosed which include recurring polymeric subunits preferably made up of dicarboxylic monomers such as maleic anhydride, itaconic anhydride or citraconic anhydride. Free radical polymerization is used in the synthesis of the polymers. The polymers may be complexed with ions and/or mixed with fertilizers or seeds to yield agriculturally useful compositions. The preferred products of the invention may be applied foliarly or to the earth adjacent growing plants in order to enhance nutrient uptake by the plants.
