Usage

Uses

Used in Plastics Industry:
Tris(decyl) phosphate is used as a flame retardant and plasticizer for enhancing the fire resistance and flexibility of various plastic materials.
Used in Adhesives Industry:
Tris(decyl) phosphate is used as a flame retardant and plasticizer to improve the fire safety and workability of adhesives in bonding applications.
Used in Coatings Industry:
Tris(decyl) phosphate is used as a flame retardant and plasticizer to increase the fire resistance and durability of coatings applied on different surfaces.
However, there is some concern about the potential health and environmental impacts of tris(decyl) phosphate, as it is considered a toxic substance and may have the potential to bioaccumulate in organisms. Despite this, it continues to be used in the manufacturing of many industrial and consumer goods due to its effectiveness in inhibiting the spread of flames and reducing the flammability of materials.

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.

Solvent-free microwave synthesis of trialkylphosphates

Trialkylphosphates are synthesized from alcohols by reaction with reactive phosphorus oxychloride under microwave irradiations and classical heating. Effects of these irradiations on the nature of the products and on the yield are studied. The compounds were characterized by their spectroscopic data and elemental analysis. The obtained results show that the products of these reactions are essentially trialkylphosphates and alkylphosphoric acids. They always show as the nature of the formed products and the yields in trialkylphosphates are comparable to those obtained in the classical conditions of heating. The speed of the reaction was increased by a factor from 40 to 120.

Absolute viscosity and density of trisubstituted phosphoric esters

This paper presents measurements on the absolute viscosity (η) and density (ρ) of trisubstituted phosphoric esters which are useful in understanding their flow mechanism necessary for accessing their role as plasticizers. The effect of chain length and branching has been examined on the η and ρ trends. From η data, by using the Vogel-Tammann-Fulchur (VTF) equation, the VTF temperature (To) has been obtained which also represents the ideal glass transition temperature. To is related to the flexibility of the molecules. It is observed that To initially decreases with molecular weight, reaches a minimum, and increases thereafter. The initial decrease in To has been attributed to the enhanced flexibility of the phosphate esters. Reversal of flexibility with relative molar mass beyond 400 is due to the gentle collision of the arms of the trisubstituted phosphoric esters. This has been further corroborated from the molar mass exponent as exhibited in the η-molar mass plot. The isomeric effect on η has also been investigated in tricresyl phosphates, hitherto for the first time. The ortho isomer has highest η among the isomers. The para isomer was found to have lowest To and hence highest flexibility compared to the ortho and meta isomers.
