Description
Technical field
The invention belongs to herbicide field more particularly to a kind of pretilachlors and the production method of fenclorim complex microemulsion.
Background technology
Pretilachlor is the rice terrace herbicides special for having high selectivity, is dissolved in most organic solvents, to water during use
Rice safety, broad weed-killing spectrum is mainly used for preventing and kill off grassy weed and broad leaved weed, for soil treatment can prevent and kill off barnyard grass in paddy field,
Difformed galingale herb, needle spikesedge herb, Monochoria vaginalis, alisma canaliculatum etc. are used in rice direct seeding field and rice seedling bed, and elder generation is whole well, and then vernalization is broadcast
It is applied when planting 2-4 days, soil treatment before bud can only be made, weed seed absorbs medicament in germination process, is prevented and kill off suitable for rice
1 year raw grass family such as barnyard grass, bald barnyard, moleplant seed, eleusine indica, needle spikesedge herb, alisma canaliculatum and broad leaved weed.Fenclorim appearance is
Colourless crystallization, is dissolved in acetone, cyclohexanone, dichloromethane, toluene, dimethylbenzene, and the main application of fenclorim is detoxified as herbicide
Agent, for protecting the wet infringement for broadcasting rice from pretilachlor, while on the growth rate of rice without influence.Product of the present invention is with the third grass
Amine, fenclorim are major ingredient, are made up using organic solvent, surfactant, water of auxiliary material of a series of blending techniques, the producer
Method has using common apparatus, simple for process, reaction condition is mild, pollution-free waste discharge, good product quality etc. are a series of
Advantage, product good dispersion in water, activity is high, suitable for preventing and kill off 1 year raw grass family and broad leaved weed before rice tooth.
The content of the invention
Present invention mainly solves the problem of be to provide a kind of pretilachlor and fenclorim complex microemulsion, produce the product use
Raw material include by weight ratio：Pretilachlor 10-11%, fenclorim 5-6%, acetone 22%, benzene sulfonic acid sodium salt 2%, water 60%.
The present invention can be achieved through the following technical solutions：
（1）First the acetone of formula ratio is added in the first agitator tank, starts to stir under room temperature, the rotating speed of blender for 25 turns-
30 revs/min, sequentially add pretilachlor, the fenclorim of formula ratio while stirring, be stirred to react 0.4-0.5 it is small when；
（2）First the water of formula ratio is added in high-speed stirred tank, starts to stir under room temperature, the rotating speed of blender is 20 turn -25
Rev/min, the benzene sulfonic acid sodium salt of formula ratio is added in while stirring, is stirred to benzene sulfonic acid sodium salt and is all dissolved；Heighten stirring in fast agitator tank
The rotating speed of device is 190-200 revs/min, will slowly be dissolved in pretilachlor, the fenclorim addition high-speed stirred tank of acetone, and be stirred to react
Finished product is obtained after when 0.5-0.6 is small.
The present invention further technical solution be：
The pretilachlor purity is 80%, the purity of fenclorim is 80%.
Step（1）, step（2）The room temperature is 2-35 DEG C.
The beneficial effects of the invention are as follows：Provide a kind of pretilachlor and the preparation method of fenclorim complex microemulsion, the party
The advantages of method is：It is simple for process, environmental pollution is small, the reaction time is short, reaction condition is mild, product good dispersion in water, living
Property it is high, it is harmless to rice suitable for preventing and kill off 1 year raw grass family and broad leaved weed before rice tooth.
