first grade diethyl phthalate as plasticizers for polymers

pharmaceutical applications of plasticized polymers

Pharmaceutical Applications of Plasticized Polymers

plasticizers include triace tin, acetylated monoglycer ide and diethyl phthalate. Acrylic polymers as a group of various synthetic polymers, methacrylic amino ester copolymers, have diverse functionality in film coating. They can be used for rapidly disintegrating coatings, taste and odour masking, coloured or transparent coatings, etc., and

Diethyl Phthalate - an overview | ScienceDirect Topics

Cyclohexanedicarboxylic acid esters or hexahydrophthalate esters have been used as plasticizers for many years, first being prepared in Germany by the hydrogenation of lower molecular weight phthalates, dimethyl phthalate, diethyl phthalate, and possibly dibutyl phthalate. These were offered as nitrocellulose plasticizers in the 1930s [21]. In ...

Diethyl phthalate | C12H14O4

In the human intestinal preparation, the diethyl phthalate hydrolase activity was 31.2-153 nmol/hour/mg in the duodenum and 129 nmol/hour/mg in the jejunum. Similarly, of the tissues from three rat and one human studied in vitro, the rat small intestine hydrolyzed the greatest amount (36.4%) of diethyl phthalate in a 16-hour period.

Plasticizer - Dibutyl Phthalate Manufacturer from Mumbai

Dibutyl phthalate (DBP) is an organic compound which is commonly used as a plasticizer because of its low toxicity and wide liquid range. With the chemical formula C 6 H 4 (CO 2 C 4 H 9 ) 2 , it is a colorless oil, although commercial samples are often yellow.

Eastman DEP - Eastman - datasheet - Polymer Additives

Diethyl phthalate. Used as a plasticizer. Has good stability to heat and UV light and very good resistance to hydrolysis. Can be used alone or in combination with other plasticizers to provide solvency and plasticizing for a wide range of resins and polymers. Because of its relatively high volatility, DEP is seldom used in polyvinyl chloride ...

aqueous polymer dispersion, it is first dissolved and/or dispersed wi thin the outer water phase. Subsequently, the plasticizer diffuses in to the polymer particles. A sufficient amount of time for plasticizer uptake by the polymer particles is necessary to avoid forming an inhomogeneous plasticized system (Bodmeier Paeratakul, 1997).

Enteric Coating: An Overview

Cellulose acetate phthalate, also known as cellacefate is the oldest and most widely used synthetic enteric coating polymer. It was patented as an enteric agent in 1940 by Eastman Kodak Company. CAP is synthesized by reacting a partial acetate ester of cellulose with phthalic anhydride in the presence of a tertiary organic base such as pyridine ...
