Regarding the 2011 Industrial Structure Adjustment Catalogue’s restrictions on epichlorohydrin produced by saponification method
Thread Content
On April 26, 2011, the Development and Reform Commission issued the 2011 Catalogue for Industrial Structure Adjustment. On page 65, under the category of restricted items, there is an entry for “epichlorohydrin production facilities using the saponification method”. What does this mean? Let’s discuss it together!
“\"Epoichlorohydrin production plant using the saponification method\" – this represents a restriction on the use of this process, and new projects utilizing it are not permitted.
Oh! I forgot that currently, there are three manufacturing methods worldwide: the propylene high-temperature chlorination method, the acrylate method, and the glycerol method for epichlorohydrin.
Right now, there’s a lot of hype around the glycerin method
Strictly speaking, the industrial production of epichlorohydrin currently uses the saponification method, with dichloropropanol being saponified to produce epichlorohydrin. Whether using propylene as the raw material or glycerin as the raw material. Using exchange resin as a saponifying agent is merely a roundabout way of carrying out saponification
Reply to 5# jjf278204: That means everything is restricted! ? If there are restrictions, there must be a reason for them, right? What is the amount of wastewater discharged? High energy consumption? It is unknown.
Therefore, there is a problem with the definition of the saponification method itself
Restrictions are not prohibitions; if scale or environmental issues are properly addressed, it is still possible to allow the project to proceed. This is why it is listed as a restriction. If the technology is outdated and pollution is severe, then it’s definitely classified as prohibited. :)
