固体酸催化剂怎么使用?? 我们做过一些固体酸作用下的脱水、酯化及醚化反应！不知道楼主用的是那类催化剂。分子筛类固体酸，首先要保证是h氢型的，使用之前500度焙烧一下。杂多酸类使用之前250度以下热处理。气固相反应的话，可以在使用前用惰性气体、原位加热处理！可以参考：catalytic synthesis of diphenylmethane from benzene and formalin with water-tolerant solid acids applied catalysis a: general, volume 216, issues 1–2, 1 august 2001, pages 147-155condensation of benzene and aqueous formaldehyde to diphenylmethane in a biphasic system consisting of an aqueous phase of heteropolyacid journal of molecular catalysis a: chemical, volume 206, issues 1–2, 1 october 2003, pages 121-130synthesis of dimethyldiphenylmethane over supported 12-tungstophosphoric acid (h3pw12o40) journal of molecular catalysis a: chemical, volume 243, issue 2, 16 january 2006, pages 233-238synthesis of dimethyl ether (dme) on modified hy zeolite and modified hy zeolite-supported cu–mn–zn catalystsapplied catalysis a: general, volume 304, 10 may 2006, pages 49-54selective synthesis of para–para′-dimethyldiphenylmethane over h-beta zeolite catalysis today, volume 131, issues 1–4, 29 february 2008, pages 378-384microwave assisted in situ synthesis of usy-encapsulated heteropoly acid (hpw-usy) catalysts applied catalysis a: general, volume 352, issues 1–2, 15 january 2009, pages 259-264core–shell structured cuo–zno@h-zsm-5 catalysts for co hydrogenation to dimethyl etherfuel, volume 96, june 2012, pages 419-425， 查看更多
