3-甲基-5-叔丁基-1,2-苯二酚苯甲酸酯(二酚酯) - Introduction

3-Methyl-5-tert-butyl-1,2-phenylene dibenzoate is an organic compound with the chemical formula C21H22O3. The following is a description of its nature, use, formulation and safety information:

Nature:
-Appearance: White crystalline powder or crystal
-Density: approx. 1.10g/cm³
-Melting point: About 176-180 ° C
-Solubility: Soluble in common organic solvents such as ethanol, ketones and benzene

Use:
-Ternary catalyst: Diphenol ester can be used as one of the components of the ternary catalyst for the preparation of polyurea and polyurethane.
-UV Absorber: Diphenol ester absorbs ultraviolet rays to protect substances from damage by ultraviolet radiation, so it is often used as a UV absorber for cosmetics, plastic products and coatings.

Method:
Diphenol ester can be synthesized by transesterification. A common preparation method is the transesterification of benzoic acid esters with 3-methyl-5-tert-butyl-1, 2-benzenediol in the presence of an alkaline catalyst to produce diphenolates.

Safety Information:
Diphenol esters are generally relatively safe under regular handling. But here are some caveats:
-Decomposition may occur at high temperatures to produce dangerous gases, so it should be operated under proper ventilation conditions.
-Avoid contact with strong oxidants to prevent fire or explosion.
-Wear appropriate personal protective equipment such as safety glasses, gloves and laboratory suction equipment during use.
-If you accidentally inhale or touch your skin/eyes, wash them immediately and seek medical help.
