摘要：
A catalyst for glycerin dehydration of the present invention comprises boron phosphate or a rare-earth metal phosphate, wherein a molar ratio P/B of phosphorus (P) to boron (B) or a molar ratio P/R of phosphorus (P) to a rare-earth metal (R) is more than 1.0 and 2.0 or less. An another catalyst for glycerin dehydration of the present invention comprises a combination of boron phosphate and a metal element or a combination of a rare-earth metal phosphate and a metal element other than a rare-earth metal, wherein a molar ratio M/(P+B) of a metal element (M) to phosphorus (P) and boron (B) or a molar ratio M/(P+R) of a metal element (M) to phosphorus (P) and a rare-earth metal (R) is more than 0.00005 and 0.5 or less.
