Phloroglucinol Impurity 21 - Reference Information
| LogP | 0.895 at 25℃ |
| NIST chemical information | information provided by: webbook.nist.gov (external link) |
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| purpose | used in organic synthesis, preparation of various Ether derivatives; Used for printing drawings; Analysis reagent. mainly used in organic synthesis |
| production method | is obtained from the reaction of resorcinol with dichlorothioyl. Resorcinol and diethyl ether were mixed, heated to reflux with stirring, and dichlorosulfuryl was slowly added dropwise. Then warm to 60 degrees Celsius for 1H. The ether was recovered and then subjected to atmospheric distillation, and the distillate was further distilled under reduced pressure to collect a fraction of 131 ° C. (0.8-0.93kPa) or 160-164 ° C. (4.0kPa) to obtain a finished product. |
