Production methodprocess of Pivaldehyde Liquid

• I. Pivaldehyde CAS 630-19-3 is produced by formylation of Grignard's reagent, the reaction formula is as follows Because of Grignard's reagent and the reaction need to strictly control the reaction conditions, the product yield is lower (only 57%~61%), and the raw material cost is more expensive, so it causes the production cost to be too high.
• Secondly, Pivaldehyde Liquid was produced by reductive hydrolysis of pivaleronitrile as raw material, and the reaction formula was as follows, although the yield of the product in this step was high (up to 89%). However, due to the raw material pivaleronitrile need to be prepared by pivalic acid or tert-butyl bromide, and may be involved in the high temperature reaction of the reinforced phase or highly toxic cyanide, the operation is more troublesome, the total yield is not ideal, especially the catalyst lithium trialkoxyaluminum hydroxide is expensive, its practical value is not very large.
• Third, the catalytic reduction of pivaloyl to produce Pivaldehyde Raw Materials, the reaction formula is as follows The method has the advantages of relatively simple operation process, low cost of raw material pivaloyl chloride, rich sources, but the required catalyst toxicity, pollution is serious, and the use of the catalyst products with a low yield of only 32%.
• IV. A method for synthesizing Pivaldehyde Raw Materials, characterized in that: using pivaloyl chloride as the raw material, using palladium-carbon poisoned by quinoline-S as the catalyst, carrying out a reduction reaction with hydrogen in a solvent to which an acid-binding agent has been added, and the reaction solution is sequentially filtered, washed, extracted, dried and distilled.
