Bis(2-ethylhexyl) terephthalate commonly abbreviated DEHT (Dioctyl terephthalate or DOTP), is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2.It is a non-phthalate plasticizer, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol, which is often generically referred to as octyl.
Bis(2-ethylhexyl) phthalate (di-2-ethylhexyl phthalate, diethylhexyl phthalate, diisooctyl phthalate, DEHP; incorrectly — dioctyl phthalate, DIOP) is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2. DEHP is the most common member of the class of phthalates, which are used as plasticizers.
Benzenedicarboxylic acid is a group of chemical compounds which are dicarboxylic derivatives of benzene. Benzenedicarboxylic acid comes in three isomers: Phthalic acid (1,2-benzenedicarboxylic acid) Isophthalic acid (1,3-benzenedicarboxylic acid) Terephthalic acid (1,4-benzenedicarboxylic acid)

Phthalates (US: / ˈ θ æ l eɪ t s / UK: / ˈ (f) θ æ l eɪ t s ˌ ˈ (f) θ æ l ɪ t s / [1] [2]), or phthalate esters, are esters of phthalic acid. They are mainly used as plasticizers , i.e., substances added to plastics to increase their flexibility, transparency, durability, and longevity.
Diisobutyl phthalate (DIBP) is a phthalate ester having the structural formula C 6 H 4 (COOCH 2 CH(CH 3) 2) 2. It is formed by the esterification of isobutanol and phthalic anhydride. This and other phthalates are used as plasticizers due to their flexibility and durability.
Synthesis of bis(2-ethylhexyl)-tetrabromophthalate (TBPH) from tetrabromophthalic anhydride and 2-ethylhexanol. In this general synthesis method, tetrabromophthalic anhydride and 2-ethylhexanol are used as raw materials in a molar mass ratio of 3-7:1.
General structure of 1,2-, 1,3-, and 1,4-dicarbonyls. In organic chemistry, a dicarbonyl is a molecule containing two carbonyl (C=O) groups.Although this term could refer to any organic compound containing two carbonyl groups, it is used more specifically to describe molecules in which both carbonyls are in close enough proximity that their reactivity is changed, such as 1,2-, 1,3-, and 1,4 ...
