Usage

General Description

Phosphoric acid di-n-decyl ester is a chemical compound composed of phosphoric acid and di-n-decyl alcohol. It is commonly used as a surfactant in industrial and household products such as detergents, cleaning agents, and lubricants. As a surfactant, it lowers the surface tension of liquids, allowing them to spread and penetrate more easily. It also acts as an emulsifier, helping to mix substances that normally do not blend well, such as oil and water. Phosphoric acid di-n-decyl ester is known for its ability to effectively remove dirt, grease, and oil, making it a valuable ingredient in various cleaning and degreasing applications. However, it is important to handle this chemical with care as it can cause irritation to the skin and eyes, and may be harmful if ingested.

A process for preparing didecyl calcium phosphate method and its application

The invention provides a preparation method of didecyl calcium phosphate and an application thereof. The preparation method comprises the following steps: (1) making decanol carry out reactions with phosphorus oxychloride in the presence of pyridine so as to obtain oxidized didecyl phosphate; wherein the volume ratio of the pyridine to the phosphorus oxychloride is 1:2; (2) subjecting the oxidized didecyl phosphate to hydrolysis and acidification so as to obtain didecyl phosphate; (3) making didecyl phosphate carry out reactions with saturated CaCl2 at a temperature of 38 to 42 DEG C to generate didecyl calcium phosphate; wherein the solvent in the reaction system is a aprotic polar solvent. The preparation method of calcium phosphates is very simple, and assists the promotion and application of calcium ion selective electrode.

Convenient preparation of long-chain dialkyl phosphates: Synthesis of dialkyl phosphates

Reaction of phosphorus oxychloride with a primary alcohol (1.8 equiv) and triethylamine (1.8 equiv) in toluene, followed by filtration and treatment with steam, gives dialkyl phosphates in good yield and essentially free from trialkyl phosphate contamination.
