Synthesis of Surface Active Agents. IV.

Surfactants - Surface Active Agents

The definition for a detergent is a cleaning agent. The main cleaning agent used in earlier days was soap. This term means a compound formed from the reaction of a fatty acid with a base such as caustic soda, forming the sodium soap of the acid. The more commonly used cleaning agent in this day and age is the synthetic detergent (SYNDET) which is a formulation such as TIDE or FAB. The essential...

Synthesis of Some New Piperazine-iV^iV'-bis-substituted Derivatives As Potential Biologically Active Agents

In a search for new bactericidal and fungicidal agents some new piperazine-TV, TV'-bis-substituted derivatives have been prepared and characterized by their elemental analysis, IR, *H N M R , and mass spectral d a t a . T h e ant ibacter ia l and antifungal activities of all p repared c o m p o u n d s have been determined using Gentamycin as s t a n d a r d antibiotic. Some c o m p o u n d s s...

synthesis and characterization of potentially biological active cyclometallated organoplatinum(ii) complexes

this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...

Surface active agents as tumor promoters.

*TUC Centenary Institute of Occupational Health London School of Hygiene and Tropical Medicine, Keppel St., London WC1E-7HT, England. the types of promoter listed have not been demonstrated as such by animal experiments, but if a substance is a carcinogenic but not mutagenic, then it is most probably a tumor promoter. This assumes that mutagens are initiators and that promoters can induce cance...
