    Abstract: PROBLEM TO BE SOLVED: To obtain an excellent herbicide, to provide a method for preparing the herbicide and a method for using the herbicide. SOLUTION: A method for suppressing the growth of undesirable plants in the site comprises applying at least one kind of compound represented by formula (I) [wherein X represents N or CR ; R represents a halogen atom, an alkyl group, an alkenyl group, or the like; R represents hydrogen atom or R ; R represents hydrogen atom, formyl group, an alkyl group, or the like; A represents an aryl group, a nitrogen-containing heteroaromatic group or thienly group; Z represents oxygen or sulfur atom or single bond; (m) is 0 or 1 or 2] or its salt permissible on crop culture or N-oxide thereof.

    Abstract: PCT No. PCT/EP96/04818 Sec. 371 Date May 18, 1998 Sec. 102(e) Date May 18, 1998 PCT Filed Nov. 5, 1996 PCT Pub. No. WO97/19069 PCT Pub. Date May 29, 1997A process for distilling ethylene oxide out of a mixture including ethylene oxide in a column at an absolute pressure of from 2 to 10 bar and a temperature of 20 to 180 DEG C. by withdrawing pure ethylene oxide in the liquid or gaseous state overhead or via a sidestream in the rectifying section of the column includes effecting the distillation in a column having on its inside a plurality of successive zones of structured sheet-metal packing or dumped beds of packing elements, these zones being assigned one or more extinguishing systems on the outside of the column.

    Abstract: In a pure ethylene oxide distillation process, an aqueous mixture containing ethylene oxide, formaldehyde and at least 5 % by weight water is supplied via an inlet to a distillation device with at least one distillation column at a height above the column bottom of at least 8 theoretical stages. The ethylene oxide is removed at the head of the column and a mixture is obtained at the bottom of the column with less than 5 % by weight ethylene oxide.

    Abstract: In a process for purification of ethylene oxide by distillation an aqueous mixture comprising ethylene oxide, formaldehyde and at least 5% by weight of water is introduced via a feed into a distillation apparatus comprising at least one distillation column, the mixture being introduced at a height above the bottom of at least 8 theoretical stages, the ethylene oxide is taken off at the top and in the bottom phase a mixture is obtained which contains less than 5% by weight of ethylene oxide.
