Problems solved by technology

[0003] The widely reported catalyst for the preparation of 2-propyl-1-heptanol by the hydrogenation of 2-propyl-2-heptenal is Raney nickel catalyst, which is more effective, but the catalyst is expensive, and there are problems in storage and transportation. great danger
Johnson Matthey Catalysts' HTC NiO series catalysts can also be used to catalyze the hydrogenation of 2-propyl-2-heptenal. According to reports, the content of 2-propyl-1-heptanol in the product is about 96%. However, the raw material is a mixed feed of 2-propyl-1-heptanol and 2-propyl-2-heptenal, which has the problem of high subsequent separation costs

Description

technical field [0001] The invention relates to the field of organic synthesis, in particular to a catalyst for synthesizing 2-propyl-1-heptanol. Background technique [0002] 2-Propylheptanol (2-PH) is the preferred raw material for the synthesis of environmentally friendly phthalate plasticizers. Plasticizer is the most demanded variety among plastic additives. The largest consumption field of plasticizers is soft polyvinyl chloride (PVC) products, of which phthalate plasticizers account for 88%. DOP (dioctyl phthalate) and DEHP (diisooctyl phthalate) are general-purpose plasticizers with excellent comprehensive performance, which have the advantages of good plasticizing performance and relatively low price. However, due to safety issues, the production and consumption of DOP in developed countries have declined sharply since the late 1990s. From 2004 to 2008, BASF launched a new product - di(2-propyl)heptyl phthalate (DPHP) in Europe and the United States, which was pr...
