Eupergit oxirane acrylic beads: how to make enzymes fit for biocatalysis.
The epoxide group is also known as oxirane and glycidyl group.
In the spectrum of the modified oil, it is also evident the presence of absorption bands at 1,228 [cm.sup.-1] and 1050 [cm.sup.-1], attributed to the presence of -C-O-C- groups formed during the reaction, as well as the characteristic bands for oxirane rings at 848 and 910 [cm.sup.-1], confirming the presence of epoxy groups in the modified mixture.
Stapperfenne, Reemers, and Hallack produced a fiber laminate consisting of two or more aluminum sheets and a textile fabric with an anhydrous uretdion oxirane hardener.
These monomers are basically a hybrid composed of siloxane and oxirane rings.3,4 The ring opening mechanism is also responsible for reduced shrinkage and high reactivity when compared to conventional methacrylate based resin composites.5
2,2,3-trifluoro-3-(trifluoromethyl) oxirane was reclassified as non-mutagenic, as reported in the ECHA CHEM database (8) with reliability 1 according to the Klimisch score (Klimisch et al., 1997).
Epoxidation of fatty acids is a reaction of a carbon-carbon double bond with active oxygen, which results in the addition of an oxygen atom, converting the original double bond into a three membered epoxide (oxirane) ring (Figure 1).
The role of the hydrogen bond between the oxygen atoms of the oxirane ring and the hydrogen for hydrogen bonding of the hydroxyl group during the aminolysis of epoxy compounds has been considered in a number of works.
The reaction was on the oxirane group of the epoxydized oils which is considered as amidolysis process .
The result revealed that the major essential oils from turmeric rhizomes are Eucalyptol (76.46%), [alpha]-Terpinene (4.41%), [gamma]-Terpinene (3.32%), p-Cymene (1.31%), and [alpha]-Terpineol (0.62%) while [alpha]- Zingiberene (17.43%), [beta]-Sesquiphellandrene (3.10%), Eucalyptol (2.75%), Furfaral (1.76%), [alpha]-Terpineol (1.35%), endo-Borneol (1.31%), Limonene (1.21%), Thunbergol (0.84%), Citral (0.56%), Oxirane (0.45%), Caryophyllene oxide (0.42%), Nerolidol (0.31%), exo-Norborneol (0.27%), cis-Verbenol (0.12%), Linaloloxide (0.06%), and Squalene (0.02%) are the major essential oil compounds detected in ginger rhizomes.
Progress in attenuation of the 3010-3006 [cm.sup.-1] band of the olefin with time and increasing formation of the oxirane band around 840 [cm.sup.-1] was monitored in 30 min intervals of the reaction.
