摘要:
Disclosed are fluorobenzene derivatives, which are important intermediates for producing herbicidal oxazolidinedione derivatives, and methods of producing them. The fluorobenzene derivatives include compounds of a formula (11): ##STR1## where X is a halogen atom, R.sup.3 is a nitro, amino or isocyanato group or R.sup.1 OCONH, and R.sup.1 is an alkyl or phenyl group. Via the intermediates of the invention, oxazolidinedione derivatives can be produced with high yield.

摘要:
A benzene derivative substituted with a heterocyclic ring represented by the general formula: ##STR1## wherein R represents a cycloalkyl group having 3 to 8 carbon atoms, X represents a halogen atom, and Z represents ##STR2## in which said cycloalkyl group may be substituted with an alkyl group having 1 to 6 carbon atoms, a process for preparing the same, and a herbicidal agent comprising the above compound as an active ingredient are disclosed. The compound has an excellent effect in that the compound exhibits a markedly high herbicidal effect on weeds in the field and the paddy field at a low dose and yet exhibits markedly low noxious effects on main crops.

A process is disclosed for preparing 2-chloro-4-fluorophenol which comprises chlorinating 4-fluorophenol with a chlorinating agent in the presence of water. The process according to the present invention has advantages in that the chlorination can be carried out using inexpensive reagents without requiring the use of particular apparatus and under mild conditions, and the desired product can be obtained in good yields and with high selectivity. 2-Chloro-4-fluorophenol obtained in the present invention is useful as a starting material for producing various pharmaceutical agents and agricultural agents.
摘要:
A surface electrode (5) is installed on the light receiving surface of a solar cell element, the surface electrode (5) comprises three bus bar electrodes (5a) for extracting light-produced at the solar cell element to the outside and collecting finger electrodes (5b) connected to these bus bar electrodes (5a), and the bus bar electrodes (5a) are not less than 0.5 mm and not more than 2 mm in width and the finger electrodes (5b) are not less than 0.05 mm and not more than 0.1 mm in width. A high-efficient solar cell module can be obtained with substantially lowered resistance by increasing the number of bus bar electrode (5a) and thereby decreasing the lengths of the finger electrodes (5b).
摘要:
An object of the present invention is to provide a method for efficiently recovering solid selenium or gaseous selenium from wastewater/waste using a microorganism. The present invention provides a method for recovering selenium, comprising reducing a water-soluble selenium compound so as to produce elemental selenium or gaseous selenium by allowing a sample containing a water-soluble selenium compound to come into contact at a temperature which is more than 35° C. and is 40° C. or less at pH 7.0 to 9.4 with a microorganism capable of producing elemental selenium or gaseous selenium through reduction of a water-soluble selenium compound.
