What is Propoxur?
Propoxur, chemical name: 2-isopropoxyphenyl-N-methylcarbamate, is one of the four carbamate insecticides recommended by WHO to prevent and control health pests. It has contact, stomach toxicity and fumigation effects. It has a wide range of insecticides, quick knockdown, low residue and long lasting effect. With the wide application of pyrethroids such as permethrin and cypermethrin in recent years, the resistance of health pests such as mosquitoes and flies to pyrethroids has been greatly improved. Experiments show that, Propoxur has a unique sensitivity to these resistant pests.
The prior art involves the combination of propoxur and some pyrethroid active ingredients, such as permethrin, (highly effective) cypermethrin, fenvalerate, fenpropathrin, cyhalothrin, cyhalothrin, permethrin, etc. However, the existing combination of these sanitary insecticides has poor control effect, knockdown and resistance. However, The combination of propoxur and selected pyrethroid compounds in a specific ratio has unexpected technical effects.
Among them, new highly effective knockdown pyrethroid compounds such as dextran trans cypermethrin, tetrafluorofenvalerate, heptamethrin, mefenvalerate, and tetrafluoropermethrin have the best combination effect with propoxur. These five insecticides themselves have excellent knockdown effect on mosquitoes and flies of health pests, and their lethality to mosquitoes is slightly insufficient, but their lethality to houseflies is strong, which is easy to produce resistance when used alone. However, propoxur has a certain knockdown effect on mosquitoes and excellent lethality, while it is slightly insufficient for houseflies. After the combination of pyrethroid and propoxur, the synergism of pyrethroid on mosquitoes and flies is very obvious, and the knockdown and lethality have been greatly improved.

Preparation of Propoxur
Proxacarb is a carbamate insecticide, which is mainly used for the control of economic crop pests and the elimination of various sanitary pests in households and public places. It has the characteristics of wide insecticidal spectrum, long residual effect and high insecticidal rate.
At this stage, there are three methods of synthesizing propoxur:
1. Chloroformate method, the method process is more complicated;
2. Methylcarbamoyl chloride method, which has serious environmental pollution;
3. Methyl isocyanate method, although this method has simple process flow and less three wastes, the reaction yield is generally below 90%:
In a glass reactor, add o-isopropoxyphenol and catalyst, n (phenol): n (catalyst) = 1: 0.001 ~ 0.05; stir and cool, slowly add methyl isocyanate (MIC), n (phenol) : n(MIC)=1:1～1:1.2; after the dropwise addition, the reaction is carried out at 60～110° C. for 0.5～3h.
