| description | The invention relates to the field of catalytic chemistry, and discloses a preparation method of 1, 1-dialkoxy alkane, the preparation method is as follows: in the presence of a catalyst, subjecting alcohol as shown in R1OH and aldehyde as shown in R2-CHO to a contact reaction, wherein the catalyst is a hydrogen type EWT structure molecular sieve, R1 is methyl, ethyl, propyl, butyl or pentyl, and R2 is hydrogen, methyl, ethyl, propyl or butyl. According to the method, a molecular sieve type catalyst with a hydrogen type EWT structure is adopted and has higher reaction activity and better acetal yield.
本发明涉及催化化学领域，公开了一种1,1-二烷氧基烷烃的制备方法，其中，所述制备方法包括：在催化剂的存在下，将R1OH所示醇与R2-CHO所示醛接触反应，所述催化剂为氢型EWT结构分子筛，所述R1为甲基、乙基、丙基、丁基或戊基，所述R2为氢、甲基、乙基、丙基或丁基。该方法采用了氢型EWT结构的分子筛型催化剂，其具有更高的反应活性和更佳的缩醛收率。 |
