    摘要: Potentiated insect repellent compositions comprising a combination of Deet and certain bicyclic lactones having insect repellent properties are disclosed. The lactones comprise compounds of the formula: ##STR1## or the corresponding unsaturated compounds thereof having the formula: ##STR2## wherein R, R', R" and R"' each are lower alkyl or hydrogen; wherein y is an integer from 1-3, and x and z each are 0 or 1, with the proviso that y is 1 or 2 when x is 1. Preferably, R, R', R" and R"' each are hydrogen or methyl. Such compositions preferably further include a carrier. A method of using such a potentiated composition to repel an insect from a situs comprises applying to such situs an effective amount of the composition, with or without the carrier.

    摘要: A single-stage quadrupole mass analyzer is provided with a highly sensitive electron multiplier, a turbomolecular pump, and a mass correction lens placed between the quadrupole sensor unit and the turbomolecular pump. These components are arranged and selected to provide a substantial increase in sensitivity permitting the direct analysis of organic compounds in the gas phase in the ppb and high ppt concentration range. The placement of the mass correction lens and the area of its aperture has a pronounced effect on the detection limit, the optimum aperture area is a function of the mass of the molecules to be detected, and preferably an iris diaphragm is used to permit manual of automatic adjustment of the aperture area to a predetermined optimum for each of the different substances to be detected. Preferably the electron multiplier voltage is also variably selected and reset during the scanning of each fragment ion to optimize the signal-to-noise ratio of the electron mutiplier. The mass analyzer is sufficiently compact and economical to provide on-site analysis and the continuous monitoring or control of industrial processes.

    摘要: Novel pesticidal compositions, which are characterized by biodegradability and do not bioaccumulate to an unacceptable level in fats and tissues of animals, fowl and fish, containing active compounds and optionally a carrier suitable for administering said compounds to a pest by contact, ingestion or inhalation, are disclosed. Such compositions comprise in addition to the carrier compounds of the formula ##STR1## where R is H, Cl or other Hal, hydroxyl, lower alkoxyl, lower alkyl, cyano, CONR.sub.2 or NR.sub.2 where R.sub.2 is H or lower alkyl; X and Y may be R, and when taken together may be --O-- or a saturated or unsaturated monocyclic or bicyclic group which may be substituted with R, epoxide, carboxy or carboxymethyl group; and the unsaturated analogs thereof wherein the unsaturation occurs at at least one of the 2 or the 5 positions, and wherein unsaturation may occur optionally in the ring formed by X and Y taken together; with the further proviso that said compound has between 4 and 6 halogens; and a carrier for said compound. Methods of using such pesticides to kill or disable pests are disclosed. Certain novel compounds within the group and novel methods of making said compounds are disclosed.
