  硼砂作为一种有效的无金属催化剂，用于水性介质中的杂迈克尔反应

  摘要：

  硼砂是一种天然存在的材料，在水性介质中非常有效地催化硫醇、二硫醇和胺与 α,β-不饱和酮、腈、酰胺、醛和酯的共轭加成，在室温下以良好的收率提供相应的迈克尔加合物. 催化剂的再循环和反应的放大是这种催化的重要属性。硫醇和二硫醇的反应比相应的胺更容易。

  The invention provides a dispersant for an aqueous dispersion of boehmite particles which comprises a compound having an anchoring moiety linked to a polymeric hydrophilic moiety, the anchoring moiety containing at least one acid and/or hydroxy group and having overall acidity or neutrality and the polymeric moiety having a lower affinity for a boehmite surface than the anchoring moiety. The anchoring moiety preferably contains at least two acid groups, preferably carboxylic acid groups, attached either in a [1,1], [1,2] or [1,3] relationship and is linked to the polymeric moiety, which is preferably derived from acrylamide or methacrylamide monomer units, preferably by a sulfur atom. The dispersant can reduce the viscosity of the boehmite dispersion and the tendency of the boehmite dispersion to increase in viscosity and/or form a gel or a yield stress material following periods of high shear stress. It may be used, for example, as a component of a coating material, a ceramic, paint, refractory material, filler, or in particular in an inkjet recording paper or film, wherein good porosity and gloss is maintained by the use thereof.

  The invention provides a dispersant for an aqueous dispersion of positively charged or chargeable solid particulates which comprises a compound having an anchoring moiety linked to a polymeric hydrophilic moiety, the anchoring moiety containing at least one acid and/or hydroxy group and having an overall acidity or neutrality and the polymeric moiety having a lower affinity for the particulate surface than the anchoring moiety. The anchoring moiety preferably contains at least two acid groups, preferably carboxylic acid groups, attached either in a [1,1], [1,2] or [1,3] relationship and is linked to the polymeric moiety, which is preferably derived from acrylamide or methacrylamide monomer units, preferably by a sulfur atom. The dispersant can reduce the viscosity of an aqueous dispersion of positively charged or chargeable solid particulates and can reduce the tendency of the resulting dispersion to form a gel or a yield stress material. The dispersant facilitates the processing of the resulting compositions in manufacturing operations and it may be used, for example, as a component of a coating material, a ceramic, paint, refractory material, filler or in an inkjet recording paper or film. Additionally, the dispersant can allow the use of higher concentrations of solid particulates and enable control of the yield stress, as some yield is often beneficial in helping prevent or reduce sedimentation.

  The invention provides a dispersant for an aqueous dispersion of negatively charged or chargeable solid particulates which comprises a compound having an anchoring moiety linked to a polymeric hydrophilic moiety, the anchoring moiety containing at least one basic group and having an overall basicity and the polymeric moiety having a lower affinity for the particulate surface than the anchoring moiety. The invention also provides a coating composition containing the dispersant, an inkjet recording element containing the dispersant and methods of coating or reducing viscosity using the dispersant.

  The present invention provides a method for reducing the level of acrylamide in a food product, comprising: (a) applying an acrylamide reduction agent in alkaline solution onto a food material before heat treating the food material; and (b) heat treating the food material to form the finished food product, wherein due to application of the thiol agent in alkaline solution, the finished food product comprises reduced level of acrylamide compared to a product which has not been treated with the acrylamide reduction agent in alkaline solution before heating. In addition, the present invention provides a food production produced by the method of the present invention.
