摘要:Polyether (meth)acrylates based on cyanuric acid or substituted cyanuric acid and multifunctional alcohol, which optionally include triethanolamine units, have wide applications in UV curable adhesives, coatings, inks, sealants, paints or 3D printing. These polyether acrylates have rigid cyanurate structure endowing the material with extra strength and thermal stability. Furthermore, triethanolamine unit, when present, endows the material with anti-oxygen inhibition property in UV curing process. These polyether (meth)acrylates have low viscosity and high reactivity towards UV curing. The cured resins have high resilience and strength. The process of making the polyether (meth)acrylates includes the synthesis of trifunctional polyether polyols through controlled polymerization of propylene oxide using multifunctional alcohol (such as glycerol and sucrose), cyanuric acid or substituted cyanuric acid, and optionally triethanolamine, in the presence of a catalyst, followed by the synthesis of polyether (meth)acrylates through transesterification or through direct esterification of the trifunctional polyether polyols.

标题:Method for recovering molybdenum catalyst values and use of said values in the recycling of said catalyst
发明人：MAURIN JEAN
权利人:RAFFINAGE CIE FRANCAISE
摘要:This application is directed to a method for regenerating catalyst values used in the synthesis of a diol; the synthesis consists of a hydroperoxide reaction with an olefin in the presence of water and a molybdenum catalyst; the regenerating process consists in treating the molybdenum catalyst residue (or a fraction thereof) with ammonia -- optionally after calcining -- and causing a diol to act on the ammonium molybdate so obtained; in one embodiment ammonia in gaseous form is passed in contact with a catalyst residue (not previously calcined) which is in solution; the reaction products in the synthesis of the diol are a hydroperoxide such as tertiary hydroperoxide of isopentane and an olefin such as methyl 2-butene; the diol synthesized in 2-methyl 2,3-butanediol; it is also the synthesized diol which is preferably reacted with the ammonium molybdate.
