Surface-active fungicides

Dimeihylamine, C2H7N, (CH3)2NH. Colourless, inflammable liquid with an ammoniacal odour, mp -96" C, b.p. 7°C. Occurs naturally in herring brine. Prepared in the laboratory by treating nitrosodimetbyl-aniline with a hot solution of sodium hydroxide. Dimethylamine is largely used in the manufacture of other chemicals. These include the solvents dimethylacetamide and dimethyl-formamide, the rocket propellant unsym-metrical dimethylhydrazine, surface-active agents, herbicides, fungicides and rubber accelerators. 

Benzyl-derived quaternary ammonium compounds are used widely as cationic surface-active agents and as germicides, fungicides, and sanitizers. Benzyl alcohol is used in a wide spectmm of appHcations including pharmaceuticals and perfumes, as a solvent, and as a textile dye assistant. 

Polyalkylene polyamines find use in a wide variety of applications by virtue of their unique combination of reactivity, basicity, and surface activity. With a few significant exceptions, they arc used predominantly as intermediates in the production of functional products. End-use profiles for the various ethyleneamines include fungicide, oil and fuel additives, polyamides/epoxy curing, paper resins, chelaiing agents, fabric sofieners/surfactanls, petroleum production, bleach activator, and anlhelmimics/pharmaceulicals. 

Alkylboron acids and their ethers are used as additives to engine fuels. Some alkylboron acids (nonyl- and dodecylboron) are bactericides, fungicides, surface active agents. They can be used as additives to petrol, as reactants in the synthesis of polymers and as stabilisers of aromatic amides. 

Figure 17 Cross-sectional view of the self-association of surface-active molecules into an idealized micelle. Hydrophobic portion of each surface-active molecule shown as a jagged line hydrophilic portion shown as a circle. Hydrophobic pesticide molecules, represented by the fungicide hexachlorobenzene, will tend to accumulate within the hydrophobic core of the micelle at a higher concentration than in the bulk aqueous phase. Ionic species, (e.g., hydroxide ion), will show the opposite distribution (after J. H. Fendler and E. J. Fendler, 1975).

It is common to add a dispersing agent in the formulation to obtain good and stable dispersion of the filler and to prevent sedimentation. Other surface active ingredients such as defoamers and/or air release agents are usually added to prevent foam and/or air bubbles in the adhesive. Biocides/fungicides are also added to prevent microbial growth. 

More recently, self-assembling 3//-azepine monolayers on a gold surface have been obtained by the photodecomposition of bis ll-[(4-azidobenzoyl)oxy]undec-l-yl disulfide.284 Other than some alkyl and aryl 177-azepine-l-carboxylates, which possess fungicidal activity, particularly against Sclerotium rolfsii,104 the unsaturated azepine systems surveyed in this section do not have any notable biological activity.
