Usage

General Description

Diisobutyl terephthalate (DIBT) is a chemical compound that belongs to the group of phthalates, which are esters of phthalic acid. It is commonly used as a plasticizer in the production of various types of polymers, including PVC, to impart flexibility and durability to the final products. DIBT is also utilized in the manufacturing of adhesives, sealants, and coatings, where it acts as a softening agent. Additionally, it is found in some personal care products and cosmetics as a fragrance ingredient. While DIBT has many industrial applications, concerns have been raised about its potential adverse effects on human health and the environment, prompting regulatory measures to limit its use in certain products.

ESTER-BASED COMPOUND, COMPOSITION COMPRISING THE SAME, METHOD FOR PREPARING THE SAME AND RESIN COMPOSITION COMPRISING THE SAME (AS AMENDED)

The present invention relates to an ester-based plasticizer composition, a method for preparing the same and a resin composition comprising the same. The ester-based plasticizer composition according to one embodiment of the present invention is a novel terephthalate-based ester compound for a plasticizer prepared through transesterification. When the ester-based plasticizer composition is used in a resin composition, it is capable of providing excellent resistance for stress, and excellent physical properties such as migration resistance and volatility resistance as well as tensile strength and elongation rate.

Low-melting mixtures of di-n-butyl and diisobutyl terephthalate

Mixtures of terephthalate diesters having lowered freezing points and methods of making the terephthalic acid diesters. The method includes contacting a first alcohol, a second different alcohol and dimethyl terephthalate in the presence of a catalyst to thereby form the terephthalate diesters.
