Evaluations of repellents for Hippelates eye gnats was written by Axtell, Richard C.. And the article was included in Journal of Economic Entomology in 1967.Category: alcohols-buliding-blocks The following contents are mentioned in the article:
Twenty chemicals or combinations of chemicals were evaluated for their repellency toward H. pusio with turntables in the field. Some of the materials were also tested against H. bishoppi and H. pallipes. The most effective repellents for H. pusio were: Triple Mix (63.8% di-Me phthalate + 18.8% Indalone (butyl 3,4-dihydro-2,2-dimethyl-4-oxo-2H-pyran-6-carboxylate) + 17.3% ethylhexanediol), MGK (McLaughlin Gormley King Co.) Formula 5780 (75% ethylhexanediol + 4% MGK 264 (N-2-ethylhexyl)-5-norbornene-2,3-dicarboximide) + 1% MGK Repellent 11 (1,5a,6,9,9a,9b-hexahydro-4a-(4H)-dibenzofurancarboxaldehyde) + 1% MGK Repellent 326 (di-Pr 2,5-pyridinedicarboxylate)), butyl-acetanilide, and butylethylpropanediol. Less repellency was shown by TMPD (2,2,4-trimethyl-1,3-pentanediol) + 8% di-Me phthalate, TMPD, and ethylhexanediol. Other materials exhibited little or no repellency. H. bishoppi was generally repelled by those chemicals which were effective against H. pusio but some exceptions indicated definite differences in the sensory responses of these 2 species. Limited tests indicated that a repellent that is effective against H. pusio is not necessarily effective against H. pallipes. Four repellents applied to human skin were tested for their effectiveness against caged laboratory-reared gnats. The frequency of gnat landings on the treated skin of the forearms was used as the index of effectiveness. The repellency of deet, Triple Mix, and ethylhexanediol declined to 50% of the initial level in about 110 min. and TMPD in about 60 min. This study involved multiple reactions and reactants, such as 2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4Category: alcohols-buliding-blocks).
2-Butyl-2-ethylpropane-1,3-diol (cas: 115-84-4) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Category: alcohols-buliding-blocks
