本文合成了N,N-二甲氨基甲酸苯酯、4-氯苯酯、2,4-二氯苯酯、萘酯、4-氯萘酯、2,4-二氯萘酯等6种,并比较其杀虫效力,借以了解芳核上代入氯原子对杀虫作用的影响.对家蝇触杀作用,以苯核上代入2个氯原子的效果较好,萘核上代入氯原子对家蝇的触杀作用有所降低,而其一氯取代物对蚊蚴的浸杀效力略有增强. In this paper, 6 kinds of phenyl N, N-dimethylcarbamate, 4-chlorophenyl, 2,4-dichlorophenyl, naphthyl, 4-chloronaphthalene and 2,4- And to compare their insecticidal efficacy, in order to understand the aromatic nucleus into the chlorine atom on the insecticidal effect on housefly contact effect, substituting the two benzene nuclei on the chlorine atom is better, substitution of chlorine atoms on the nuclear naphthalene home The contact effect of the flies decreased somewhat, while the effectiveness of the chlorine monoxide substitution on mosquito larvae slightly increased.
