- Efficient organic solvent and oil sorbent co-polyesters: Poly-9-octadecenylacrylate/methacrylate with 1-hexene
-
In this work, highly absorbent cross linked co-polymer gels of cis-9-octadecen-1-ol with acrylic/methacrylic acid and 1-hexene in different molar ratios were synthesized by thermal polymerization techniques and studied. The polymers were characterized by

- Lipid modified spermine derivatives and the use of the derivatives of the prepared liposome
-
The invention provides a liposome-modified spermine derivative and a liposome prepared by the derivative. The spermine derivative is directly applied or is mixed with one or more selected from cholesterol, neutral lipids and polyethylene glycol (PEG)-modified lipids, which can be adopted as a carrier for entrapping or absorbing bioactive molecular drugs to be loaded into cells. In this way, the effect of regulation, intervention or treatment is realized. In a general formula (1), X1 represents -(CH2)- or carbonyl group, wherein n represents 1, 2 or 3; X2 represents -(CH2)-, ester group, amide group, oxygen, or sulfur; R1 and R2 independently represent C6-C18 alkyl group or lipophilic cholesterol molecules, respectively.

- A three-step-one-pot chemo-enzymatic synthesis of epoxyalkanolacylates
-
Using the ability of Novozym 435 to catalyze both the perhydrolysis and the interesterification of esters, unsaturated primary alcohols are converted with an ester and hydrogen peroxide to give esters of epoxidized alcohols directly in a convenient three-step-one-pot synthesis with yields of 66-89%.
