A containing 2, 6 - di-tert-butyl phenol anti-oxidant and its preparation method

The invention reveals a 2,6-di-tert-butylphenol-containing anti-oxidant and a novel preparation method thereof. The method takes titanium, zirconium, hafnium, bismuth, antimony metal complexes as green catalysts, a two-step system is substituted by a series reaction one step method technology, and a high efficiency metal complex catalyst capable of simultaneously catalyzing a direct esterification reaction and a Michael addition reaction is employed to prepare the novel anti-oxidant. The method takes acrylic acid (or acrylic acid ester), pentaerythritol and 2,6-di-tert-butylphenol as main raw materials, under organic solvent or solvent-free condition, the titanium, zirconium, hafnium, bismuth, antimony metal complex green catalysts are reacted to obtain the novel anti-oxidant with high yield. The method has the advantages of low cost, high yield, simple operation and no pollution, and has certain feasibility for realizing industrial production. The preparation method is the green approach with low cost.

Process for the Preparation of (Meth)Acrylates of Tetra-Or Polyhydric Alcohols

Process for the preparation of acrylic and methacrylic acid esters by transesterification of (meth)acrylic acid esters of the formula I: where R1 is H or CH3 and R2 is an alkyl radical having 1 to 40 carbon atoms, with alkanols which have four or more esterifiable hydroxyl groups, characterized in that 0.01 to 10% by weight, based on the total reaction mixture, of lithium amide catalysts are used as transesterification catalyst.
