20100041916 | PROCESS FOR PRODUCTION OF SULFONIC ACID ESTER - The present invention provides a method for producing a sulfonate ester efficiently and in high yield. | 02-18-2010 |
20120130089 | METHOD FOR PRODUCING CYCLIC SULFONIC ACID ESTER AND INTERMEDIATE THEREOF - The present invention is directed to provide an efficient production method which is capable of not only obtaining a cyclic sulfonic acid ester (sultone) at low cost and in high yield, but also the sulfonic acid ester (sultone) stably even in a commercial scale. The present invention relates to a method for producing hydroxysultone comprising a first step where a diol having a specified structure and a thionyl halide are reacted to obtain a cyclic sulfite having a specified structure, and a second step where the cyclic sulfite is reacted with water or/and alcohol; a method for producing an unsaturated sultone having a specified structure comprising a third step where a hydroxylsultone having a specified structure is reacted with an acid halide or an acid anhydride to obtain an intermediate, subsequently the intermediate is treated with a base; as well as a cyclic sulfite having a specified structure. | 05-24-2012 |
20120130107 | PROCESS FOR PRODUCTION OF BIS-QUATERNARY AMMONIUM SALT, AND NOVEL INTERMEDIATE - Object To provide a method for producing a bis-quaternary ammonium salt efficiently and a novel synthetic intermediate thereof. | 05-24-2012 |
