US Patent 9605198 Mixed carbon length synthesis of primary Guerbet alcohols

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 comprising at least two different chain length primary alcohols and reacting the mixture of primary alcohols to produce a mixture of Guerbet alcohols. The mixture of Guerbet alcohols is then used to produce an additive composition comprising additives of different molecular weights.
