Combusition of polymers and the effect of fore retardant additives : a mechanistic approach.
CHAPTER 1 This chapter constitutes a general description of the combustion of polymers and the various processes involved. Processes like gas‑phase reactions, surface reactions and solid‑phase reactions are discussed in ... -
Dihydrobenzenes in organicsynthesis
The thesis entitled “Dihydrobenzenes in Organic Synthesis” consists of three chapters. Chapter I Chapter I deals with a brief introduction to the addition of electrons to unsaturated systems, in particular monobenzenoid ... -
INVESTIGATIONS ON Positive Temperature Coefficient of Resistance OF POLYCRYSTALLINE BARIUM TITANATE
The way similar to monomerisation or at higher temperatures. CD studies indicated no major change in the secondary structure of the proteins of lipovitellins during chloroform absorption. The interaction of Ca²? and Na? ... -
Kinetics and mechanism of the transient behaviour of magnesium anodes
The main objective of the present investigation is to study the mechanism of delayed dissolution of magnesium anodes during discharge of magnesium dry cells. A supplementary part of the work is devoted to the development ... -
Some reactions of oximes and related topics
The thesis entitled “Some Reactions of Oximes and Related Topics” is divided into four chapters. Chapter I This chapter describes a new reaction of oximes wherein ?? and ??acetoxyenamides (2, 3) are obtained from ketoximes ... -
Studies in oxidation of aromatic substrates
The thesis entitled "Studies in Oxidation of Aromatic Substrates" is divided into four chapters. Chapter I starts with a brief review of the reactions of organic substrates with peroxydisulphate. This chapter describes the ... -
Studies in the stereochemistry of alkylation importance of gegenion co-ordination
This thesis describes investigations into the effects of methyl and ester functions as substituents syn-axial to the ?-centre in 6-cyclic carboxylic esters when ?-enolate formation is attempted. The effects manifest ... -
Studies of hydrazinium salts
The present investigation aims at synthesis, characterization, reactivity, thermal properties and applications of some of the hydrazinium salts. In the introductory Chapter, a literature survey on the chemistry of hydrazine ... -
Studies on some bildegradable polymers
The graft copolymerization of methyl acrylate, ethyl acrylate and acrylonitrile onto gelatin in aqueous medium was necessarily heterogeneous and was not simple enough for studying the kinetic and mechanistic aspects of the ... -
Studies on synthetic methods
Conversion of amidomethyl function into aldehyde group Amidomethylated aromatic derivatives on treatment with N-bromosuccinimide produced the corresponding aromatic aldehydes in good yields. Attempted introduction of ... -
