| titleOfInvention | Production of 1,7-di(4-hydroxyphenylthio)-3,5-dioxaheptane |
| abstract | PURPOSE: To produce the titled compound useful as a color developer of leuco dyes, with simple operation, in high yield and purity, by hydrolyzing 4-thiocyanophenol under alkaline condition, and reacting with bis(2-haloethoxy)methane. n CONSTITUTION: 4-Thiocyanophenol is hydrolyzed in the presence of excess alkali (e.g. NaOH, KOH, etc.) to obtain 4-mercaptophenol. The objective compound is produced by adding bis(2-haloethoxy)methane to the reaction mixture, and reacting preferably in the presence of a phase transfer catalyst (e.g. a quaternary ammonium salt) at 15W40°C. The amount of bis(2-haloethoxy)methane is 0.5mol per 1mol of 4-mercaptophenol, and the reaction of the mixture is carried out by using 0.1mol of the catalyst. n COPYRIGHT: (C)1985,JPO&Japio |
