DOW-BASF

Liquid-Ph se Processes. Prior to 1980, commercial hquid-phase processes were based primarily on an AIQ. catalyst. AIQ. systems have been developed since the 1930s by a number of companies, including Dow, BASF, Shell Chemical, Monsanto, SociStH Chimique des Charboimages, and Union Carbide—Badger. These processes generally involve ethyl chloride or occasionally hydrogen chloride as a catalyst promoter. Recycled alkylated ben2enes are combined with the AIQ. and ethyl chloride to form a separate catalyst—complex phase that is heavier than the hydrocarbon phase and can be separated and recycled. 

HarsNet is a thematic network project sponsored by the European Commission s Industrial and Materials Technologies Program. It is coordinated through the Instituto Quimico de Sarria, with participation by government organizations, universities, major companies (e.g., Dow, BASF, and CIBA), and private testing services. 

Further reduction in the residual monomer level for food packaging applications (Dow, BASF, etc.). 

Let us recall that by the sol-gel method one can obtain very efficiently very well-defined systems such as Ti silicalite, which can be considered as a single site system where titanium is tetracoordinated in a zeolitic matrix and undergoes epoxidation of propylene or hydroxylahon of benzene to phenol. Bear in mind that it took industry more than 20 years to realize such an industrial processes (Dow-BASF process) [1]).

The H P plant, built jointly by Dow, BASF and Solvay, has a capacity of230 000 tons yr , based on the RAQ/RAHQ route for HP production. The 300000 metric-tons per year H PPO single-train plant, built jointly by BASF and Dow, started up in 2008. In 2007, Dow and Solvay also announced an agreement to create a joint venture for theconstructionofaHP plant in Map Ta Phut, Thailand. The plant will be the largest... 

The 0x0 process is the principal one in practice today only minor quantities, mainly in Europe, are obtained from separation from fusel oil. tert-Arayi alcohol is produced on a commercial scale in lower volume by hydration of amjienes (Dow, BASF) (92). 

Key players in the development and commercial application of technology for the manufacture of PO are Dow-BASF, Degussa-Uhde, ENI-Sumitomo, and ARCO/LyondeU, as Hsted in Table 1.10. Based on a Chinese patent search, there is also a focused effort in China in this area. Efforts to contact several of the authors did not elicit a response, and thus further information could not be included in this review.
