高錳酸鉀改性煤基活性炭催化合成環己酮乙二醇縮酮The traditional catalyst used in acetal ( ketal ) synthetic reaction is strong inorganic acid. but there is some limits to its use because of its side reaction, strong erosion and liability to pollute the environment. molybdophosphoric acid is used as catalyst and three condensation products are prepared through the direct reaction of aldehydes ( ketones ) and ethylene. in addition, several elements of affecting the reaction is researched. it is proved that molybdophosphoric acid is very active as catalyst in less addition, the product yield is quite high and the quality of reuse is quite good
縮醛（酮）合成反應的傳統催化劑為無機強酸，但由於副反應多、腐蝕性強和易污染環境等缺點，其使用受到限制.用磷鉬酸為催化劑，通過醛（酮）與乙二醇直接反應得到了三種縮合產物.對影響反應的諸因素進行研究，結果表明，用磷鉬酸作催化劑，用量小，活性高，產品收率較高，且重復使用性能較好Abstract : the traditional catalyst used in acetal ( ketal ) synthetic reaction is strong inorganic acid. but there is some limits to its use because of its side reaction, strong erosion and liability to pollute the environment. molybdophosphoric acid is used as catalyst and three condensation products are prepared through the direct reaction of aldehydes ( ketones ) and ethylene. in addition, several elements of affecting the reaction is researched. it is proved that molybdophosphoric acid is very active as catalyst in less addition, the product yield is quite high and the quality of reuse is quite good
