Abstract: A packaging set for solid articles including a container for accommodating the solid articles therein, and a film cover made of breakable thin film fixedly secured on the opening edge of the container so as to hermetically seal the opening of the container, and a casing including a case having a mouth corresponding to and slightly smaller than that of the opening of the container, and lid lid detachably set onto the case so as to be able to move to close or open the mouth of the case. Side edges of the mouth of the case are applied to press onto the film of the cover of the receptacle to break the film at portions corresponding to at least three sides of the opening of the container. All the solid articles in the container are thus able to transfer into the case at one time, leaving the broken film behind with the container.

Abstract: Disclosed is a process for producing a heterocyclic compound having as the side chain group a nitromethylene group of the formula: ##STR1## wherein Y, R and n are as defined in the specification, which comprises reacting a 2,2-dihalonitroethylene compound with a 1-aminoalkanethiol compound or a 1-N-substituted derivative thereof.

Abstract: Disclosed is a process for producing a heterocyclic compound having a nitromethylene group as the side chain, of the formula ##STR1## wherein Y represents a hydrogen atom, a halogen atom or a lower alkyl group, R represents a hydrogen atom, an alkyl group, a cycloalkyl group, an aralkyl group, an alkenyl group, an alkynyl group or an acyl group, and n represents an integer of 2, 3 or 4,which comprises reacting a 2,2,2-trihalo-1-nitroethane compound with a 1-aminoalkanethiol compound or a 1-N-substituted derivative thereof.

Abstract: There is disclosed a 5-mercapto-1,2,3-thiadiazoles composition comprising a 5-mercapto-1,2,3-thiadiazole combined with (A) one or more compounds selected from the group consisting of water, an alcohol, an aromatic hydrocarbon and a halogenated hydrocarbon and (B) a halide of an alkali metal and process for preparing the same.Said composition can remarkably reduce the explosiveness of a 5-mercapto-1,2,3-thiadiazole to make its handling easy and to make it usable for various applications with a sense of security, for example, for manufacturing pharmaceuticals and agricultural chemicals.

Abstract: A process for the preparation of a urea derivative having the formula: ##STR1## in which A represents a straight- or branched-chain alkyl group having 1-20 carbon atoms, an aryl group, or a heterocyclic group, and each of R.sup.1 and R.sup.2 represents hydrogen, a straight- or branched-chain alkyl group having 1-20 carbon atoms, an alicyclic group, or an aryl groups, which comprises:reacting sodium salt of an N-halogenamide with a quaternary ammonium salt to obtain its addition salt and then,reacting said addition salt with an amine derivative in the absence or presence of an organic solvent.

Abstract: 3-Alkoxy-4-hydroxyphenylacetic acid useful as intermediate for preparation of pharmaceuticals is prepared by catalytic reduction with hydrogen using a palladium catalyst of corresponding 3-alkoxy-4-hydroxymandelic acid occurring as the reaction product between 2-alkoxyphenol and glyoxylic acid at high conversion and yield.

Abstract: In a process for preparing an o-alkoxy-p-allylphenol comprising reaction of an o-alkoxyphenol with an allyl halide in the presence of an aqueous solution of an alkali metal hydroxide or alkaline earth metal hydroxide, the improvement which comprises employing a copper-containing compound such as a water-soluble copper salt, an ammine copper complex salt etc., as the catalyst. The process for preparing an o-alkoxy-p-allylphenol which comprises reaction of an o-alkoxyphenol with an allyl halide in an aqueous ammonia is also disclosed.
