Diffusion and Chemical Reaction of Sulphuric Acid in Rigid Polyvinyl Chloride Film

The Contribution of Molecular Diffusion in Silica Coating and Chemical Reaction in the Overall Rate of Reaction of Aluminum Hydroxide with Fluosilicic Acid

The kinetic of the heterogeneous chemical reaction of aluminum hydroxide and fluosilicic acid was studied. It was found that the diffusion of the reactants through the porous silica coating to the aluminum hydroxide surface and the interfacial chemical reaction between the diffusing reactant and aluminum hydroxide platelets control the overall reaction rate. These two phenomena were studied...

Synthesis and evaluation of nanohydrogel film containing polyvinyl alcohol/hyaluronic acid/zinc oxide for wound dressing

Background and Aim: Lesions of the skin can impair its vital function to protect humans against external pathogens. Therefore, producing a suitable wound dressing to repair injuries is always one of the challenges of researchers. The present study aims to Synthesize a hydrogel film for wound dressing applications. Methods: In this research, a hydrogel film of polyvinyl alcohol / hyaluronic a...

Estimation of monosaccharides by the orcinol-sulphuric acid reaction.

Fatal Chemical Peritonitis due to Sulphuric Acid Ingestion

Sulphuric acid is a strong corrosive and is widely used in laboratories, industries, and even in households. In addition to incidents of accidental poisoning, its easy availability has seen it being employed not uncommonly as a suicidal and homicidal agent. A case is presented wherein sulphuric acid was consumed to commit suicide, which ended in fatality, even though immediate and adequate medi...

Thermal Degradation of Polyvinyl Chloride

A survey is given of the recent advances in the study of and the present knowledge of the thermal degradation of polyvinyl chloride. The sites for initiation of the thermal degradation, the mechanism of the dehydrochiorination, the discolouration of PVC by heat and the influence of plasticizers on the rate of degradation are discussed.
