Title:
Ｎ−ビニルアミドの製造方法およびそれに用いられるアパタイト
Document Type and Number:
Japanese Patent JP5663964
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing an N-vinylamide which attains extremely high conversion and selectivity in the production of an N-vinylamide by dealcoholation reaction of N-(α-alkoxyalkyl)amide, and a catalyst used in the method.SOLUTION: According to the method, an N-vinylamide is produced by subjecting N-(α-alkoxyalkyl)amide to dealcoholation reaction in the presence of a surface-modified apatite catalyst prepared by surface-modifying an apatite represented by general formula (1) with a phosphoric acid compound. (In the formula, M is at least one member selected from the group consisting of Mg, Ca, Sr, Ba, Pb, Mn and Cd; Z is at least one member selected from the group consisting of P, As and Sb; X is at least one member selected from the group consisting of OH, F, Cl, Br, I and At; and 0≤y<1).
