Whether it is for the production of our largest single product, 2-Chloro- N,N-diethylethylamine hydrochloride, or for the manufacture of chlorination reagents and downstream fine chemicals or for custom synthesis, chlorination reactions are of central significance to SGR’s products.
For environmental protection, we always convey chlorination reagents in closed systems. Gaseous secondary products or by-products from the chlorination processes are recycled and or converted into suitable secondary products which can be sold in to market.
- Backward integration into reagents and chlorinated intermediates
- Sustainable production processes
- Efficient chlorination in batch processes
- Environmentally friendly recycling of sidestreams.
CHLORINATION using THIONYL CHLORIDE is at core expertise for SGRL.
Molecules bearing functional groups, such as alcohols, carboxylic acids or sulfonic acids, are chlorinated using thionyl chloride as chlorination reagent, the corresponding alkyl and aryl chlorides, carboxylic acid chlorides and sulfonyl chlorides being obtained. HCl and SO2 are formed as off-gases during chlorination reactions with thionyl chloride.
SGRL can offer custom chlorination reactions within its integrated manufacturing system, in which off-gases are separated, purified and returned to the system as feedstocks. This permits sustainable production from pilot quantities to large commercial volumes using both batch and continuous processes.
This increases yield and purity and reduces the proportion of unwanted secondary products.
