权利人:JITSUBO CO LTD
摘要:Disclosed are a carrier for use for separation purpose and a method for separation of a compound which enable a chemical reaction to be performed in a liquid phase, enable a compound of interest to be separated from the liquid phase after the completion of the reaction readily, enable the separated compound to be evaluated by structural analysis or the like while the compound being bound to the carrier, and enable the compound to be separated from the carrier readily. A carrier for separation which has a reaction site capable of reacting with other compound on a benzene ring, and a long-chain group having a specified carbon atom(s) at each of the ortho-position and the para-position of the reaction site through an oxygen atom.

摘要:In an embodiment of the disclosure, mixtures of different carbon length alcohols are used as the primary feedstock for Guerbet alcohols. Specifically, embodiments relate to a method of synthesizing mixed molecular weight additives from a mixture of primary alcohols comprising, receiving a mixture of primary alcohols having greater than two different chain length primary alcohols and reacting the mixture of primary alcohols in a single reactor to produce a mixture of at least five Guerbet alcohols. The mixture of Guerbet alcohols can then be used to produce an additive or surfactant composition comprising additives or surfactants of different molecular weights.
