Triethyl Phosphite Price Trend and Forecast

Regional Price Overview

Get the latest insights on price movement and trend analysis of Triethyl Phosphite in different regions across the world (Asia, Europe, North America, Latin America, and the Middle East & Africa).

Phosphorus trichloride is treated with ethanol in the presence of a base, usually a tertiary amine, to produce triethylphosphite.The North American phosphorous trichloride market was highly volatile during the final quarter of 2021, owing to a global scarcity of yellow phosphorous caused by China's energy crisis.

However, towards the end of the quarter, offers for phosphorous trichloride had slowed slightly as supply reduced progressively as plant running rates returned to normal. Its demand remained mixed, with favourable offtakes in some segments such as surfactants and germicides, while consumption in the rubber and plasticizer segments plummeted. Triethyl phosphite prices are influenced by the prices of the raw materials.

Triethyl phosphite is used as an intermediate in the production of a variety of products, including flame retardants, optical brighteners, pesticides, antioxidants, and pharmaceuticals.

The demand for triethyl phosphite is increasing due to an increase in demand for flame retardants in various end-use industries such as electrical and electronics, transportation, and construction. To meet fire safety and prevention regulations, these industries are increasingly relying on flame retardant-based materials. The triethyl phosphite market is benefiting from this.
