含有催化劑和載體復合無機水基溶液，是一種無毒無腐蝕作用的新型防水劑。Studied the liquid - phase synthesis of butyl acetate from n - butyl alcohol and acetic acid using the supported heteropoly blue as catalyst. examed several factors imposing on esterification. the results revealed : using this catalyst, the reactions conversion percentage reaches nearly 100 %, product yield is 98. 9 %, selectivity is 98. 9 %. reusing it 10 times, the efficiency is still well. in addition, using this catalyst, the reactions temperature is mild, the reaction time is short and the equipment hasnt any erosion. furthermore, there is no “ threewastesdischarge
對以負載型雜多藍為催化劑的乙酸與正丁醇的液相酯化反應進行了研究.考察了影響酯化反應的因素.結果表明：以負載型雜多藍為催化劑，酯化反應轉化率接近100 % ，收率可達98 . 9 % ，選擇性為98 . 9 % ，重復使用10次催化效果仍好.該催化劑還有反應條件溫和、反應時間短、對設備無腐蝕、無三廢排放等優點In the thermal reactor it promotes corrosion, and in the catalystic reactor it tends to poison the catalyst.
在熱反應器中，它促進腐蝕，在催化反應器中，它能使催化劑中毒。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
文摘: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This technology is very useful for decreasing the time of hydrogenation catalyst presulfurization and the equipment eroding as well as pollution
該工藝對縮短加氫催化劑的預硫化時間，減少調備腐蝕和環境污染，具有非常積極的意義。The mo catalyst and the co catalyst prepared by impregnation reduction did not have zero - valent metals, the catalysts were not able to resist corrosion
以硼氫化納（ nabh4 ）為還原劑的浸漬還原法制備的mo 、 co催化劑並不能得到單質的金屬，而且抗腐蝕性能不好。Regular arrays of gan nanorods have been synthesized by reacting gallium and ammonia using au as a catalyst on mgo single crystal substrate treated by chemical etching
通過金屬鎵與氨氣反應，在經化學刻蝕后的mgo單晶基片表面，以金作催化劑制備出規則排列的gan納米棒陣列。Co contents will exist as zero - valent when it was prepared by thermal reduction. but it was not able to resist corrosion, either
用氫氣在800高溫下熱還原的方法制備的co催化劑能夠得到單質的co ，但是此催化劑的抗腐蝕性能也很差。For the existence of w2c, tungsten carbide catalyst is not resistant to corrosion very well
由於w2c的存在導致催化劑的抗腐蝕性能不好，而mo _ 2c催化劑抗腐蝕性能相對較好。When mo and w were put in the co catalyst, it would be more resistant to corrosion, but the catalysis activity was nearly not increased
對co催化劑採用摻雜mo或w后發現，催化劑的抗腐蝕性能增加了，但是催化劑的活性基本不變。分享友人
