The method uses commercially available and relatively inexpensive raw materials as reactants.

Abstract: A detonating energy transmittal device is provided which, when combined with even relatively low-power blasting caps, is capable of promoting and initiating the explosive detonation of liquid nitromethane, which device comprises a plurality of layers of foam material, an effective amount of frangible articles carried on at least one surface of the foam material layers and forming thereon a substantially continuous layer intermediate the adjacent foam material layer, and a cavity capable of accommodating a blasting cap and of placing said blasting cap in intimate contact with said plurality of foam material layers. Methods for detonating fluid explosives also are provided.

Abstract: Control of parasitic worm (helminth) infestations in warm-blooded animals including poultry, swine, cattle, sheep and goats by administering substituted quinoxaline adducts to infested animals. In particular, certain adducts of quinoxaline-1,4-dioxides are capable of eliminating ingestations of the pinworms Syphacia obscelata and Aspicularis tetraptera in mammals. Several of the compounds are also effective against the tapeworm Hymenolepsis nana in mammals.

Abstract: Compositions containing certain bicyclic lactones and having insect repellent properties are disclosed. Such compositions comprise a compound of the formula: ##STR1## or the corresponding unsaturated compound 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; and a carrier. A method of using such a repellent composition to repel an insect from a situs comprises applying to such situs an effective amount of the composition, with or without the carrier, and thereby repelling the insect from the situs.

Abstract: The tendency of nitromethane to detonate when used as a fuel in an internal combustion engine surprisingly has been found to be reduced by adding to the fuel a detonation reducing amount of an additive selected from the group consisting of nitroethane, 2-nitropropane, and mixtures thereof. Nitromethane fuel compositions having a reduced tendency to detonate are also provided.
