Croton oil detection reagent and application thereof

Abstract

The invention discloses a croton oil detection reagent. The croton oil detection reagent comprises the following components in parts by weight: 38-42 parts of absolute ethyl alcohol, 12-18 parts of sodium hydroxide solution, 3-8 parts of petroleum ether and 2-6 parts of dioxyacetone. The croton oil detection reagent has the beneficial effects that the detection rate of the croton oil detection reagent is higher than that of similar products by 25-40%; meanwhile, the croton oil detection reagent is simple to operate, intuitive in detection effect and quick in detection speed.

Description

technical field [0001] The invention relates to a croton oil detection reagent and application thereof. Background technique [0002] Croton oil is a highly toxic non-edible oil. In the traditional method, the way to detect croton oil is to mix croton oil and croton oil identification test solution and then heat it. A reddish-brown ring will be formed at the junction of the two liquids, which can be used as One of the items to identify croton oil. However, the detection rate of this method is low, and the detection limit is 2.5%. At the same time, cottonseed oil, rapeseed oil, and soybean oil sometimes produce a light red ring, which will affect the detection of croton oil. Contents of the invention [0003] Purpose of the present invention is exactly at the defective in the above-mentioned prior art, provides the croton oil detection reagent that is specially used in detecting croton oil. [0004] In order to achieve the above object, the technical solution provided by ...
