    摘要: A cartridge is described which is packed with a composition which comprises a mixture of at least one aliphatic aldehyde in the range of two to seven carbon atoms (C.sub.2 -C.sub.7), at least one sulfide or disulfide, ranging from one to fourteen carbon atoms (C.sub.1 -C.sub.14), at least one carboxylic acid, ranging from 4 to 6 carbons atoms, in an appropriate carrier. The use of at least one diketofuran of 5 to 7 carbon atoms is optional. The cartridge is provided with a dispensing nozzle to apply the composition to a tree trunk in the form of a closed band. When so applied, it prevents Gypsy Moth larvae and other hardwood defoliators to ascend the tree and thus interrupts the feeding cycle of these defoliators.

    摘要: A PHENOL WHICH IS UNSUBSTITUTED AT THE POSITION PARA TO THE HYDROXY GROUP OR UNSUBSTITUTED AT AT LEAST ONE OF THE POSITIONS ORTHO TO THE HYDROXY GROUP IS DISSOLVED IN A SOLVENT, IN THE ABSENCE OF HYDROGEN SULFIDE AND CATALYSTS, AND WHILE COOLING TO A TEMPERATURE BELOW 30* C. IS REACTED WITH DISULFUR DICHLORIDE. THE SOLVENT IS AN ACID AMIDE WHOSE NITROGEN ATOMS ARE COMPLETELY ALKYLATED. POLYTHIOBISPHENOLS ARE OBTAINED IN HIGH YIELD.

    摘要: BIS-(TETRAHALOETHYL) TRISULFIDES AND BIS-(TRIHALOVINYL) TRISULFIDES. THESE TRISULFIDES ARE PREPARED BY REACTING TETRAHALOETHYLSULFENYL CHLORIDE OR TRIHALOVINYLSULFENYL CHLORIDE, RESPECTIVELY, WITH HYDROGEN SULFIDE. THE TETRAHALOETHYL COMPOUNDS ARE USEFUL AS SEED DISINFECTANTS; WHEREAS THE TRIHALOVINYL MATERIALS ARE ALGICIDAL.
