Paragraph 0054-0057, (2021/09/29)
PROBLEM TO BE SOLVED: To provide a method for producing a (meth)acrylate compound containing a hydroxyl group, which, when producing a (meth)acrylate compound containing a hydroxyl group, can suppress formation of by-products. SOLUTION: Provided is a method for producing a (meth)acrylate compound (A) which is a (meth)acrylate compound containing a hydroxyl group, comprising a step of reacting an alcohol compound containing a halogen atom and a (meth)acrylic acid salt to obtain the (meth)acrylate compound (A).

Paragraph 0022; 0055, (2017/03/08)
The invention provides a synthetic method of 10-methacryloyloxydecyl dihydrogen phosphate. The method comprises the steps of preparing an intermediate 10-hydroxyldecanoyl methacrylate, preparing 10-methacryloyloxydecyl dimethoxy phosphate, and preparing the above target product. In the monoester synthesis process, a solvent-free reduced pressure distillation technology is adopted for the first time, so the environmental pollution problem caused by the use of an organic solvent is avoided, the cost is reduced, and unreacted raw materials can be recycled; in the phosphorylation process, trimethyl phosphite is adopted as an acylation reagent for the first time, and the reaction is carried out at room temperature under mild conditions, so the energy consumption is reduced, the environmental pollution problem caused by phosphorous oxychloride and other acylating agents is avoided, and the unreacted raw material 10-hydroxyldecanoyl methacrylate can be recycled; and a freeze-drying technology adopted in hydrolysis post-treatment avoids complicated operation of column chromatography and the mass use of an organic solvent, realizes low cost, environmental protection, mild reaction conditions, high product yield reaching 87.0% and high product purity, and is suitable for industrial production.
SELF-ETCHING DENTAL COMPOSITIONS AND METHODS
-
Page/Page column 39, (2008/06/13)
The present invention is directed to dental compositions that can be used as adhesives for bonding a dental material to a dental structure surface and/or as a dental restorative material. The dental composition is preferably applied to a dental structure surface under conditions effective to etch the dental structure surface.
