摘要： The present invention relates to a process for dehydrochlorinating polyvinylchloride polymers to remove about 30 wt % chlorine therefrom by heating the starting materials PVC and deoxygenated liquid water, preferably neutral liquid water at temperatures from about 200.degree. C. up to the critical temperature of water at autogenous pressure to maintain the water as a liquid phase. The process has utility in recycling by enabling PVC to be dechlorinated specifically by a means that does not release chlorine gas.

摘要： The present invention provides for a simplified process for converting ethers into their corresponding alcohols comprising forming an aqueous mixture of the ether and at least about 50% by weight water and heating the mixture under autogeneous pressure at a temperature of from about 250.degree. to 450.degree. C., more preferably from about 250.degree. C. up to the critical temperature of water which is about 374.degree. C. Heating is continued for a period of time sufficient to convert at least about 20% by weight of the ether, usually from about 5 up to about 120 minutes, depending on temperature and the amount of water present, and the identity of the starting ether feedstock.The process may be characterized as an aquathermolysis reaction wherein the reaction proceeds in water primarily through ionic routes rather than through free radical routes. Accordingly, relatively high conversion rates and good yields of alcohol and other reaction by-products may be obtained without the necessity of using a catalyst in the process.
摘要翻译：本发明提供了将醚转化成其相应的醇的简化方法，包括形成醚的水性混合物和至少约50重量％的水，并在约250-450℃的温度下在自主压力下加热混合物更优选约250℃至约374℃的水的临界温度。继续加热足够的时间以使至少约20重量％的乙醚转化成通常为约 5至约120分钟，这取决于温度和存在的水的量以及起始醚原料的特性。该方法可以表征为水解溶解反应，其中反应在水中主要通过离子路线而不是通过自由基途径进行。因此，可以获得醇和其它反应副产物的相对高的转化率和良好的产率，而不需要在该方法中使用催化剂。

摘要： The present invention relates to enhanced process for converting certain ethers, such as sec-butyl ether and isopropyl ether to their corresponding reaction products in the presence of water. This may be accomplished by adding a rate enhancing surfactant, such as an anionic or cationic surfactant to a mixture of the ether and water, preferably least about 10.sup.-5 molar surfactant. Under those conditions the reaction shows an increase in reaction rate over the rate of the process wherein surfactant is not used.

摘要： The present invention provides for a catalyst composition which is effective for use in the production of dimer products and higher olefin products from lower olefins such as propylene and butene in high yields and with an average degree of branching in the dimer products of less than about 1.6 methyl groups per molecule, generally in the range of from about 1.0 to 1.4 methyl groups per molecule. The present invention also provides a process for producing such dimer and higher olefin products using the catalyst composition of this invention. The catalyst of the invention comprises an amorphous nickel oxide (NiO) present as a disperse substantial monolayer on the surfaces of a silica (SiO.sub.2) support, which support also contains minor amounts of an oxide of aluminum, gallium or indium such that the ratio of NiO to metal oxide present in the catalyst is within the range of from about 4:1 to about 100:1. The catalyst may be prepared by precipitating a water insoluble nickel salt onto the surfaces of a silica support which has been impregnated with the metal oxide or onto a silica-alumina support which has been dealuminized such that the resulting nickel oxide/alumina ratio will fall within the ranges set forth above. The catalyst may then be activated by calcination in the presence of oxygen at a temperature within the range of from about 500.degree. to 700.degree. C.
