SORBITAN ESTERS AND PROCESS FOR ENZYMATICALLY PREPARING SAME

A process can be used for enzymatic preparation of sorbitan carboxylates. Sorbitan carboxylates are obtainable by this process.

INTEGRATED CONVERSION AND OLIGOMERIZATION OF BIO-DERIVED ALCOHOLS

Systems and methods are provided for integrated conversion of biomass to ultimately form naphtha and/or diesel boiling range products. The integrated conversion can include an initial conversion of biomass to alcohols, such as by fermentation, followed by conversion of alcohols to olefins and then olefins to naphtha, jet, and diesel boiling range compounds, with high selectivity for formation of diesel boiling range compounds. The integrated conversion process can be facilitated by using a common catalyst for both the conversion of alcohols to olefins and the conversion of olefins to naphtha and/or diesel boiling range compounds. For example, ZSM-48 (an MRE zeotype framework structure catalyst) can be used as the catalyst for both conversion of alcohols to olefins and for oligomerization of olefins with increased selectivity for formation of diesel boiling range products.

SURFACTANT PREPARATION PROCESS

An enzymatic process for the preparation of C16 alkyl polyglycosides and/or C18 alkyl polyglycosides by reacting C16 alkyl glycoside and/or C18 alkyl glycoside with a glycosyl donor containing monosaccharide residues to form an alkyl polyglycoside intermediate which can be fractionated to form an alkyl polyglycoside product, wherein the mole-average degree of polymerization mean DP) of the glycoside chains is greater than or equal to 3.0 units and the molar concentration of alkyl triglycoside (DP3) is greater than alkyl monoglycoside (DPI). The C16/C18 alkyl polyglycoside product is particularly useful in health care formulations, especially in combination with and/or as a solubilizer for active pharmaceutical ingredients (APIs).

PROCESS FOR PREPARING SURFACTANT

A process for the preparation of C4 to C24 alkyl polyglycosides by the use of an enzyme to react C4 to C24 alkyl glycoside with a glycosyl donor containing monosaccharide residues, wherein the C4 to C24 alkyl polyglycosides have a mole-average degree of polymerization (mean DP) of the glycoside chains of greater than 1.5 units.
