Embodiment 1

[0048] like figure 1 As shown, the present embodiment provides a kind of epichlorohydrin production process, and it comprises the following steps:

[0049] Step 1. Calcium carbide slag configuration

[0050] In this step, it is used to obtain calcium carbide slag emulsion containing about 20% calcium hydroxide;

[0051] Step 2, preparation of allyl chloride

[0052] In this step, it is used to obtain allyl chloride;

[0053] Step 3, preparation of epichlorohydrin

[0054] In this step, epichlorohydrin is prepared from the calcium carbide slag emulsion obtained in step 1 and the chloropropene obtained in step 2.

[0055] In this embodiment, the preparation of epichlorohydrin can be preferably realized through steps one to three.

[0056] Meanwhile, in order to realize the method in this embodiment, this embodiment also provides an epichlorohydrin production device, which includes a carbide slag configuration unit, a chloropropene unit, and an epichlorohydrin unit, and the ...

Abstract

The invention relates to the technical field of epoxy chloropropane production, and particularly discloses an epoxy chloropropane production process which comprises the following steps: step 1, calcium carbide slag preparation; step 2, chloropropene preparation; and step 3, epoxy chloropropane preparation. According to the epoxy chloropropane production process, lime waste residues discharged by a calcium carbide method PVC device are recycled and used as raw materials for cyclization reaction, and the waste residues are comprehensively utilized; mirabilite generated in caustic soda brine refining process is adopted to remove calcium chloride in the cyclization wastewater, organic matters in the cyclization wastewater are removed by using activated sludge and a deep oxidation method, and the cyclization wastewater is recycled as salt dissolving make-up water, so that the purposes of resource conservation, environmental friendliness, comprehensive utilization of wastes, no pollutant discharge, energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of epichlorohydrin production, in particular to an epichlorohydrin production process and a device thereof. Background technique [0002] Epichlorohydrin is an important organic chemical raw material and fine chemical product. It is a large variety of propylene derivatives. It is mainly used in the synthesis of glycerin, epoxy resin, epichlorohydrin rubber, nitroglycerin explosives, etc. It can also be used It is used as a solvent for cellulose esters, resins and cellulose ethers; it is also the main raw material for the production of surfactants, plasticizers, stabilizers, adhesives and ion exchange resins. It is also widely used in industries such as coatings, adhesives, reinforcing materials, casting materials and electronic laminates. In addition, epichlorohydrin can also be used in the synthesis of surfactants, pharmaceuticals, pesticides, coatings, rubber materials, ion exchange resins and other produ...
