AI Technical Summary

Technical Problem

In existing technologies, the reaction detection time for organic peroxides is long, making it difficult to accurately determine the reaction endpoint. This leads to improper control of the reaction time, resulting in significant losses and safety hazards.

Method used

The acyl chloride standard color gradient method was adopted. The standard color gradient of acyl chloride was established by the color reaction of acyl chloride, alkaline hydroxylamine hydrochloride and ferric chloride as a colorimetric reagent. The color reaction was carried out in combination with organic peroxide samples to quickly determine the reaction endpoint.

Benefits of technology

It enables rapid and accurate determination of the reaction endpoint of organic peroxides, improves detection efficiency, and reduces reaction losses and safety risks.

Abstract

The invention discloses an organic peroxide reaction endpoint rapid detection method and application thereof, and belongs to the technical field of organic chemistry. The invention aims to solve the technical problems that the reaction endpoint of an organic peroxide initiator is difficult to judge, the generated organic peroxide is easy to decompose due to too long reaction time, and the reaction is incomplete and raw materials are remained due to too short reaction time, and provides a rapid detection method for acyl chloride residues in the organic peroxide reaction process. Therefore, the reaction endpoint is determined. According to the technical scheme, the method for rapidly detecting the reaction endpoint of the organic peroxide is characterized in that in the reaction process of an organic peroxide initiator, acyl chloride is gradually consumed, the content is reduced, and the acyl chloride completely reacts when the reaction endpoint is reached. Through reaction of different acyl chloride concentrations and hydroxylamine hydrochloride, a standard curve or a color card is established, the residual amount of acyl chloride is judged, and the reaction endpoint is accurately judged.
