Disclosed is a method of repelling noxious insects comprising the step of exposing said noxious insects to a composition containing from 0.1 to 90 wt. %, based on the total weight of the composition, of at least one of 2-(1-hydroxyalkyl)cycloalkanones represented by the following formula 11:
1
wherein n is an integer of 3-10, R
1
is hydrogen or a straight-chain saturated hydrocarbon radical having 1-6 carbon atoms; R
2
is hydrogen or methyl group and R
m
′ represents m′ of the same or different, straight-chain or branched, saturated or unsaturated, hydrocarbon radicals R which, as a substituent group, can be bonded to carbocyclic atoms; m′ is an integer of 0-8, provided that m′ should be at least 2 when n is at least 4 and both the R
1
and R
2
are alkyl groups; the sum of the carbon atoms of R
m
′ does not exceed 12; and, further, when n is 4, R may be an isopropylidene group which intramolecularly bridges between the third and sixth carbocyclic atoms.
本发明涉及一种驱除有害昆虫的方法,其步骤包括将所述有害昆虫暴露于含有以下化合物之一的组成物中,所述化合物占组成物总重量的0.1至90重量%:2-(1-羟基烷基)环烷酮,其化学式为11:1,其中n为3-10的整数,R1为氢或具有1-6个碳原子的直链饱和碳氢基团,R2为氢或甲基基团,Rm'代表相同或不同的m',直链或支链,饱和或不饱和,碳氢基团R,作为取代基团,可以与环状碳原子结合;m'为0-8的整数,但当n至少为4且R1和R2均为烷基时,m'应至少为2;Rm'的碳原子总数不超过12;当n为4时,R可以是一个异丙亚甲基基团,其在第三个和第六个环状碳原子之间形成分子内桥接。
