1,4-Benzenedipentanoic acid, 2,5-dihydroxy-.delta.,.delta.,.delta.,.delta.-tetramethyl-, dihexyl ester - Introduction
dihexyl 2,5-dihydroxy-.delta.,.delta.',.delta.'-tetramethylbenzene-1,4-divalerate, also known as TMTPA, is an organic compound. The following is a description of its nature, use, formulation and safety information:
Nature:
TMTPA is a colorless to pale yellow viscous liquid. It is stable at normal temperature and soluble in common solvents such as alcohols, ethers and ketones. It has good thermal stability and can withstand high temperature and oxidizing environment.
Use:
TMTPA is mainly used as a curing agent and hardener for polyester resins. It can react with phenolic resin and epoxy resin to form high molecular polymer, which has good heat resistance, electrical properties and mechanical properties. Therefore, it is widely used in automotive, electronics, aviation and other fields.
Preparation Method:
The preparation of TMTPA is usually obtained by reacting methyl 2,5-dihydroxyphenidate with diethyl adipate. This process can be carried out under basic conditions, and the reaction temperature is generally between 100 and 140°C.
Safety Information:
TMTPA is relatively safe under normal conditions of use. However, because it can cause allergic reactions, it is recommended to wear appropriate protective measures during use, such as gloves, goggles and chemical protective clothing. In addition, avoid contact with skin and eyes, and maintain a well-ventilated working environment. If you accidentally inhale or ingest TMTPA, please seek medical attention.
