摘要： Process technology for selectively isomerizing vinylidene olefin to tri-substituted olefin is described. The vinylidene olefin, normally in admixture with other types of olefins, especially linear 1-olefins, is treated with anhydrous hydrogen bromide under anhydrous conditions and in the absence of molecular oxygen and free radical initiator. The contacting period, which can be a matter of minutes, is sufficient to selectively isomerize the vinylidene olefin to tri-substituted olefin. If the process is conducted properly, little if any hydrobromination occurs.

摘要： Tetrabromobisphenol-A is made in high purity by adding a methanol-bromine solution to a methanol-bisphenol-A solution with vigorous agitation. Use of the bromine-methanol solution reduces the amount of by-products compared to the use of liquid bromine feed to a methanol-bisphenol-A solution. The process is readily adapted to large scale equipment by circulating the reaction mixture from the reaction vessel through an external closed loop which includes an impingement mixer. The bromine-methanol feed is pumped at the proper rate and ratio into the impingement mixture whereby it impinges with the circulating reaction mixture. The resultant bromination mixture is then returned to the reaction vessel.

摘要： (Hydrocarbylthio)phenols containing at least two hydrocarbylthio groups on a phenolic ring are prepared by reacting phenolic compounds with an excess of hydrocarbyl disulfide in the presence of catalytic amounts of an aluminum phenoxide. Novel and useful (hydrocarbylthio)phenols containing at least two hydrocarbylthio groups on a phenolic ring can be prepared by this process. (Hydrocarbylthio)phenols containing at least two hydrocarbylthio groups on a phenolic ring are effective antioxidants for organic material normally susceptible to oxidative deterioration, such as mineral oil.

摘要： This invention relates to an improvement in a process for producing an alkylamine from olefin and amine by hydrohalogenating the olefin to form haloalkane then reacting the haloalkane with amine to form an alkylamine. The improvement comprises heat-treating the alkylamine thus formed with an aqueous alkaline or alkaline earth metal hydroxide at a temperature and for a period of time sufficient to minimize the formation of flocculent precipitate during the formation and/or storage of the alkylamine.
