Dienochlor is a chemical compound from the group of cyclic chlorinated hydrocarbons .
Extraction and presentation
Dienochlor can be obtained by catalytic reduction of hexachlorocyclopentadiene (e.g. with copper or hydrogen).
properties
Dienochlor is a flammable yellow solid that is practically insoluble in water. It decomposes when heated above 250 ° C. It decomposes rapidly when exposed to sunlight.
use
Dienochlor is used as an acaricide to control mites ( Tetranychus spp. , Red spider and Polyphagotarsonemus latus ) on roses, chrysanthemums and other ornamental plants.
Admission
