摘要:
The invention provides a process for preparing triazoles comprising reacting a compound having the structural formula ##STR1## with a compound having the formulaR--ON.dbd.Oin the presence of C.sub.6 -C.sub.10 alkanol, wherein n is 0, 1 or 2, R is C.sub.6 -C.sub.10 alkyl and R.sup.1 is hydrogen or C.sub.1 -C.sub.10 alkyl.
摘要:
In a positive drive power transmission system composed of a toothed belt and two or more pulleys, operating noise resulting from the impact of the belt and the pulleys is dramatically reduced by having surface discontinuities on either the belt or on the pulleys on those surfaces where the belt and the pulleys engage in impact contact when in operation. The surface discontinuities may be formed by recessed or raised portions of the belt or pulleys, may be straight or curved, and may be substantially parallel to the tensile member or at an angle thereto. Several methods of manufacturing belts with such surface discontinuities are disclosed.
摘要:
A process for making a compound of the formula ##STR1## is disclosed wherein: R is C.sub.1 -C.sub.12 alkyl, allyl or benzyl,R.sup.1 and R.sup.2 are hydrogen, halogen, C.sub.1 -C.sub.4 alkyl, or phenyl,R.sup.3 is hydrogen, halogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, CF.sub.3, NO.sub.2, phenyl or phenoxy, m is an integer from 1 to 3 andn is zero or 1,by contacting a compound of said formula where R is hydrogen with certain halohydrocarbons in the presence of solid KOH, a phase transfer catalyst, a solvent and an effective amount of water. The process of this invention permits production of the above compound, useful as a herbicide, without the need for cocatalysts or excess high concentration of NaOH and water.
摘要:
A composition, extrudable or calenderable into a membrane, comprising 100 parts by weight of a neutralized sulfonated elastomeric polymer, 40 to 250 parts of a non-polar process oil, 5 to 50 parts of a preferential plasticizer selected from the group consisting of a basic salt of a carboxylic acid and an organic amide and at least 65 parts of carbon black. The membrane, made in accordance with the composition of this invention, has particular application as a roof covering.
摘要:
An organophosphorus compound of the formula ##STR1## where R and R.sup.1 together form a 1,3-butadien-1,4-diyl group optionally substituted with a chloro group, or R and R.sup.1 together form a 1,2-ethenediylthio group wherein sulfur is attached to carbon; R.sup.2 is hydrogen, chlorine or bromine; X is O or S; R.sup.3 is C.sub.1 -C.sub.2 alkyl; and R.sup.4 is C.sub.1 or C.sub.2 alkoxy or propylthio is disclosed. The organophosphorus compounds defined above are effective in the control of insects, nematodes and acarids.
