Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this book, the synthesis of bioactive heterocyclic compounds as nonionic surfactants was studied. This study included three parts:1. Studying synthesis and reactions of enaminonitriles in producing various heterocyclic compounds using saturated fatty acids.2. Studying preparation of nonionic surface-active agents through the propoxylation process3. Studying the evaluation of the surface proprieties and biological activity of these compounds to determine using them in various industrial and applied fields. 200 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Surface active compounds holding heterocyclic ring having a dual function as antimicrobial and surface activity which may be useful in different fields as pharmaceutical and cosmetic industry, pesticides, antibiotics and fungi. Novelty of this book used for a long alkyl chain with a suitable molecular weight for the molecule becomes an amphiphilic molecule, which improves solubility, biodegradability and hence lowers the toxicity to human beings and becomes environmentally friendly. This work has been divided into three parts.1- The synthesis of heterocyclic compounds incorporated with fatty chain2- Preparation and evaluation of nonionic surface active agents3- Antimicrobial evaluation of nonionic surface active agents 232 pp. Englisch.
