General Description

2,3-dichloro-2,3-dihydronaphthalene-1,4-dione, also known as dichlone, is a synthetic organic compound with the chemical formula C10H6Cl2O2. It is a yellow crystalline substance that is used as an intermediate in the production of dyes and pharmaceuticals. Dichlone has been shown to possess antimicrobial and anticancer properties, making it a potential candidate for the development of new drugs. However, it is important to note that dichlone is toxic and should be handled with caution. It can cause skin and eye irritation, and prolonged exposure may lead to more serious health effects. Therefore, appropriate safety measures should be taken when working with this chemical.

Method for preparing 2,3-dichloro-1,4-naphthoquinone from wastes in production process of 2-chloro-1,4-naphthoquinone

The invention discloses a method for preparing 2,3-dichloro-1,4-naphthoquinone from wastes in the production process of a 2-chloro-1,4-naphthoquinone in the technical field of chemical industry. The method for preparing the 2,3-dichloro-1,4-naphthoquinone from the wastes in the production process of 2-chloro-1,4-naphthoquinone comprises the following specific steps: (S1) metering the wastes accumulated in production and feeding the wastes into a reaction kettle; (S2) feeding washed, centrifuged and dried materials into the reaction kettle again for discoloring treatment; (S3) carrying out detection through a GS gas chromatography analysis method; (S4) feeding pretreated tailings to the reaction bottle; (S5) adding industrial sodium acetate; and (S6) naturally cooling and stirring for about 30 minutes and then removing excessive chlorine. The 2,3-dichloro-1,4-naphthoquinone is prepared from waste residues generated in the production process of 2-chloro-1,4-naphthoquinone as a starting material through pretreatment and deep chlorination, so that the problem of waste residue emission is solved, the environment pressure is relieved, the environmental pollution is avoided and the production cost is reduced.
