Determination of acid value during edible oil storage using a portable NIR spectroscopy system combined with variable selection algorithms based on MPA-based strategy.

The Journal of the Science of Food and Agriculture, 2020
BACKGROUND The acid value is one of the significant indicators for evaluating the quality of edible oil during storage. Herein, this study employs a portable near-infrared spectroscopy (NIRS) system to determine the acid value during edible oil storage ...

Chemical upcycling of polyethylene, polypropylene, and mixtures to high-value surfactants

Science, 2023
Conversion of plastic wastes to fatty acids is an attractive means to supplement the sourcing of these high-value, high-volume chemicals. We report a method for transforming polyethylene (PE) and polypropylene (PP) at ~80% conversion to fatty acids with ...

Cyanoacrylates and their acid values

International Journal of Adhesion and Adhesives, 1993
Abstract Polymerization of cyanoacrylate monomer is usually initiated by the film of moisture present on the surface of the substrate to be bonded, the water neutralizing the weak acid added to inhibit the anionic polymerization reaction. In this paper, the effect of acid value on the time for polymerization of eight commercial cyanoacrylate ...

Diagnostic Value of Serum Bile Acids

Clinics in Gastroenterology, 1977
With the development of simplified methods of bile acid analysis, a new era has drawned in the evaluation of hepatobiliary disease. 1. A total serum bile acid particularly in the postprandial periods is more sensitive than either BSP or ICG for the detection of minimal liver disease and will become a useful screening method. 2.

IOPHENOXIC ACID AND SERUM-BOUND IODINE VALUES

JAMA, 1960
In 1957, Astwood 1 reported on a patient with hyperthyroidism whose serum-bound iodine level was 4,200 meg. per 100 ml. A single dose of radioactive iodine led to a clinical remission of the hyperthyroid state but the bound iodine level in the serum remained astronomically elevated.

The Fatty Acid Value Chain

2022
Directly derived from renewable biomass, i.e. plant oils and animal fats, fatty acids present themselves as polar molecules with a hydrophobic hydrocarbon chain and only two different reactive centres, a carboxyl group and olefinic double bonds. This structure makes them suitable as platforms for chemical effect species as diverse as green solvents ...
