SYNTHESIS OF VISCOSITY INDEX IMPROVER AND POUR POINT DEPRESSANT ADDITIVES FOR LUBRICATING OILS

THIS WORK IS AIMED AT SYNTHESIZING OF SOME HIGH COPOLYMERS AND TERPOLYMERS WHICH CAN BE USED TO IMPROVE VISCOSITY INDEX AND DEPRESS POUR POINT FOR LUBRICANTS. IT CAN BE A MERIT IF THESE POLYMERS ACQUIRED HIGH SHEAR STABILITY UNDER ENGINES OPERATION CONDITIONS. THE STUDY IS OCCURRED TO PRODUCE COPOLYMERIC ADDITIVES VIA BINARY COPOLYMERIZATION OF STYRENE WITH OCTYL METHACRYLATE (OCMA), DODECYL …

IMPROVING THE EFFICIENCY OF BIOFERTILED ROCK PHOSPHATE AS A SOURCE OF NATURAL PHOSPHATE FERTILIZER) BY USING SOME NATURAL AND ORGANIC ADDITIVES

FIRST WE USE A MIXTURE FROM NATURALLY BLENDED PHOSPHATES (AS A PHOSPHATE FERTILIZER) AND PHOSPHATE SOLUBILIZING BACTERIA (BACILLUS SPP.) AS A PHOSPHATE DISSOLVING ORGANISM WHICH PROCESSES THE ABILITY TO TRANSFORM INSOLUBLE PHOSPHATES IN THE ROCK PHOSPHATE INTO SOLUBLE FORMS THIS IS ACLIVED BY SECRETING OF ORGANIC ACIDS (SUCH AS ACETIC AND LACTIC ACID) USING NATURAL OR FERTILIZER, WHICH WILL BE …
