cyclohexane-1,4-diylbis(methylene) dibenzoate - Introduction
1,4-Cyclohexanediethanol dibenzoate (abbreviated as DMC) is an organic compound with the following properties:
1. Appearance: DMC is a white crystalline solid.
2. Melting point: The melting point of DMC is 132-134°C.
3. Solubility: DMC has good solubility in organic solvents, and can be dissolved in ethanol, toluene, etc.
The main uses of DMC include:
1. Polymer materials: DMC can be used as an important raw material for flexible Polyether Ester and polycarbonate, used in the preparation of polymers and their blends, polymer films, etc.
2. Coatings and inks: DMC can be used as a plasticizer for coatings and inks, which can increase the ductility and flexibility of coatings and inks.
3. Pharmaceutical intermediates: DMC can be used as an intermediate for the preparation of certain drugs, such as non-steroidal anti-inflammatory drugs and certain antibiotics.
DMC preparation method can be carried out through the following steps:
1. First, in the presence of benzene and tetrachlorocyclohexane, benzoic acid and cyclohexanediol are reacted to obtain cyclohexanediol dibenzoate.
2. Then, cyclohexanediphenol dibenzoate is reacted with formic acid and dehydrated in the presence of an acid catalyst to obtain 1,4-cyclohexanediethanol dibenzoate.
when using DMC, you need to pay attention to its security information:
1. DMC has a certain degree of irritation, should avoid contact with skin and eyes, such as contact should be washed with water immediately, and timely medical treatment.
2. DMC is a combustible substance, which should be kept away from open flame and high temperature. Avoid contact with oxidants, acids and other substances during storage.
3. When using and storing DMC, you should pay attention to good ventilation conditions and avoid inhaling its vapor to avoid poisoning.
Please note that the above information is for reference only. Please follow professional operating procedures and use safety measures in laboratory or industrial production.
