This research presents a new study in reactive distillation by adopting consecutive reaction . The adopted was the saponification of diethyl adipate with NaOH solution. occurs two steps. process had role withdrawing intermediate product i.e. monoethyl from reacting mixture before second conversion to disodium occurred. It found that appeared successfully distillate liquid. percentage di-ester m...

We have modified the procedure of Levy [Ann. C/in. Lab. Sd. 6, 474 (1972)] for determination of serum triglycerides. The changes consist of using heptane in place of normane; using concentrated aqueous potassium hydroxide instead of sodium methylate as the saponifying reagent; and a somewhat higher saponification, oxidation, and condensation temperature. Consequently, the yellow dehydrolutidine...

In the course of our ongoing work on the chemical characterization of Corsican olive oil, we have developed and validated a method for direct quantification of squalene using 13C Nuclear Magnetic Resonance (NMR) spectroscopy without saponification, extraction, or fractionation of the investigated samples. Good accuracy, linearity, and precision of the measurements have been observed. The experi...

1. The total lipid was extracted from Staphylococcus lactis I 3 with chloroformmethanol mixtures and the glycolipid component was isolated by chromatography on silicic acid. 2. Saponification yielded a non-crystalline glycoside for which the structure O-D-glucopyranosyl-(1 -÷6)-O-fi-D-glucopyranosyl-(1 -*1)-D-glycerol has been established by chemical degradations and by comparison with syntheti...

Objective: To compare the physicochemical properties of four brands vegetable oil sold in Ihiala market.
 Methods: The samples were brought from different super stores market and standard methods used to analyze various samples.
 Results: analysis showed that peroxide value, saponification values, acid ester value glycerol palm kernel (43.91 ± 0.01, 1234.20 74.14 38.56 0.02, 1195.60 0...

Due to routine maintenance of aircraft on the concrete pavement at army airbases, a large part surface is often found saturated with different hydrocarbon-based oil, fuel, and fluid. In addition, subjected aircraft’s exhaust temperature during operation. This study examined resistance ability 3 cementitious materials: (i) epoxy, (ii) fly ash (FA) based geopolymer various alkali (AL/FA) ratios (...
