摘要:使用新开发的水相沉淀晶体生长变体,可以成功合成先前未知的化合物rb 3(h 1.5 Po 4)2.该方法利用了浓溶液中沸点升高的现象.将化学计量的溶液在0.83 Atm的高蒸汽分压下从110到150oc加热,即可获得标题化合物的晶体.单晶x射线衍射研究表明,Rb 3(h 1.5 Po 4)2在空间群c2 / M中结晶并且与cs 3(h 1.5 Po 4)同构2.如通过热分析所证明的,Rb 3(h 1.5 Po 4)2在加热时不经历相变成三角超质子相.即使在蒸汽分压为0.82 Atm的情况下,将脱水抑制到263oc的温度,也没有检测到多晶型转变.该行为与cs 3(h 1.5 Po 4)2相似,并且与几种结构和化学上相似的硒酸盐化合物相反.这里开发的晶体生长方法可能证明对于获得在接近环境温度下热力学或动力学不利的水溶性化合物特别有用.

标 题 :Method for modifying catalyst performance during the gas phase synthesis of vinyl acetate
发明人：PROVINE WILLIAM DOUGLAS
权利人:DU PONT
摘要:An improved method for synthesizing vinyl acetate by the gas phase reaction of acetic acid with ethylene in the presence of oxygen. At least two catalyst modifiers are used, each causing a different level of catalyst activity. The relative mounts of the catalyst modifiers are used to fine tune the productivity of the catalyst.
