1,1,5-trimethylhepta-4,6-dienyl acetate(CAS#72214-23-4)

Introduction

2,6-Dimethyl-5,7-octadiene-2-ol acetate (abbreviated as alkyd) is an organic compound. The following is an introduction to the properties, uses, preparation methods and safety information of this compound:

Quality:

- Appearance: Alkyds are colorless or yellowish liquids.

- Solubility: It is soluble in organic solvents such as ethers, alcohols, and ketones, but insoluble in water.

- Specific gravity: It has a specific gravity of about 0.92 g/mL.

Use:

- Alkyds are widely used in industrial chemistry as solvents, diluents, and raw materials.

- It is also commonly used in the preparation of certain chemicals such as resins, coatings, and plastics.

Method:

- The preparation of alkyds is usually done by esterification, i.e. the reaction of the corresponding alcohols and carboxylic acids under acidic conditions.

- In the laboratory, an alkyd product can be obtained by heating 2,6-dimethyl-5,7-octadiene-2-ol with acetic anhydride (a carboxylic acid derivative in esterification reactions) in the presence of an acid catalyst (e.g., sulfuric acid).

Safety Information:

- Alkyds are generally considered relatively safe. During handling and use, it is still necessary to follow the corresponding safety operating procedures.

- When handling alkyds, avoid flammable gases and vapours and keep them well ventilated.
