Enzymatic synthesis of phenyl fatty hydroxamic acids from canola and palm oils.
Phenyl fatty hydroxamic acids (PFHAs) were synthesized from canola or palm oils and phenyl hydroxylamine (FHA) catalyzed by Lipozyme TL IM or RM IM. The reaction was carried out by shaking the reaction mixture at 120 rpm. The optimization was carried out by changing the reaction parameters, namely; temperature, organic solvent, amount and kind of enzyme, period of reaction and the mol ratio of ...
متن کاملSynthesis and Evaluation of Fatty Hydrazides Based on Schiff Bases from Oil Processing Industries Byproducts
Schiff bases of fatty acid hydrazides made from Oil recovered from spent bleaching earth (ORSBE) and Acid oil (AO)were prepared. These newly synthesized Schiff bases were characterized on the basis of FT-IR, elemental analysis and evaluated for biological performance. Schiff bases exhibited mild antibacterial activities against certain micro-organisms if compared with streptomycin used as stand...
متن کاملEnzymatic Synthesis of Fatty
Fatty hydrazides (FH) have been successfully synthesized from palm oils by a one-step lipase catalyzed reaction. The synthesis was carried out by treating the oils with hydrazine hydrate at neutral pH using an immobilized lipase, Lipozyme as the catalyst. The percentages of conversion of RBD (refined, bleached and deodorized) palm oil (PO), RBD palm olein (POn), RBD palm stearin (PS) and RBD pa...
متن کاملEnzymatic synthesis of fatty hydroxamic acid derivatives based on palm kernel oil.
Fatty hydroxamic acid derivatives were synthesized using Lipozyme TL IM catalyst at biphasic medium as the palm kernel oil was dissolved in hexane and hydroxylamine derivatives were dissolved in water: (1) N-methyl fatty hydroxamic acids (MFHAs); (2) N-isopropyl fatty hydroxamic acids (IPFHAs) and (3) N-benzyl fatty hydroxamic acids (BFHAs) were synthesized by reaction of palm kernel oil and N-...
متن کاملEnzymatic preparation of structured oils containing short-chain fatty acids.
Structured oils prepared by enzymatic transacylation with triacylglycerols (TAGs) and various fatty acids (FAs) were characterized. Transacylation with trilaurin and saturated FAs (C4:0-C16:0) was performed using Lipozyme RM-IM under standard reaction conditions. The structured oils thus produced had transacylation ratios of 25-37%, as medium-chain FAs > long-chain FAs > short-chain FAs. This r...
