Detailed chemical synthesis route and reaction mechanism
The manufacturing process involves the esterification of phosphorus oxychloride with excessive isobutanol. This exothermic reaction requires precise temperature control, typically maintained between 10°C and 35°C using chilled brine cooling systems to prevent side reactions. A Lewis acid catalyst facilitates the conversion, followed by a dealcoholization step under high vacuum (-0.098 MPa) to remove unreacted alcohol and hydrogen chloride gas. The crude ester undergoes simple distillation and fine distillation to achieve high purity. This multi-stage refinement ensures minimal three-waste discharge and maximizes yield, supporting competitive bulk price structures without compromising quality.
