Naturally occurring epoxy acids: ii. detection and measurement of long-chain epoxy acids by near infrared spectrophotometry*†

Journal of Lipid Research, 1961
A new method for the detection and estimation of long-chain epoxy acids in seed oils is described. It depends on the measurement of increased absorption at 2.795 μ in the near infrared spectrum caused by chlorohydrins produced from epoxides by treatment ...

SYNTHESIS OF ETHYL FATTY ALKYL ETHERS FROM COCONUT (Cocos nucifera L.) FATTY ALCOHOLS

Annals of Tropical Research, 1987
Ethyl fatty alkyl ethers were synthesized using coconut fatty alcohols as the starting raw materials. The fatty alcohols were converted into their corresponding bromides which were then made to react with ethanolic potassium hydroxide.

Detection of Solvents by Infrared Spectrophotometry

Journal of AOAC INTERNATIONAL, 1967
Abstract The solvent used in the recrystallization of a solid may be determined by use of the IR spectrum and gas cell. Recrystallized powders retain a minute amount of solvent which is not detectable in a KBr disk of the powder, but is detectable when a gas cell is vised.

Synthesis and Characterization of MnO2 nanoparticles mediated by Raphia hookeri seed

Journal of Nigerian Society of Physical Sciences
In this study, managanese dioxide nanoparticles (MnO2-NP) was synthesized. Raphia hookeri seed was used as a bioreductant for the synthesis of MnO2-NPs. The biosynthesized MnO2-NPs was investigated for their reaction, structure and morphology.

The Determination of Methimazole by Infrared Spectrophotometry

Journal of AOAC INTERNATIONAL, 1965
Abstract A method for the determination of methimazole by column chromatography and infrared spectrophotometry was subjected to collaborative study in four district laboratories. Although the results were favorable, they were not sufficiently precise nor accurate to recommend the method for adoption.
