Triethyl Phosphite Price Trend

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.
