AbstractNxB Abstract NxB and NxOB surfactant iS a borate suffactants．Which iS made up of Iong carbon chain by N-alkylation or acylation,The surface activity is greatly enhanced because of s缸-ucture ofborate surfactants and the basic property oflong carbon chain． nle borate surfactants Was synthesized from the main starting materrals such as： Aliphaticacid、alkan01、diethanolamine by acylation、halohydrocarbon、 esterification、N-alkylation．ne factors．which influenced on every reaction．were also diSCUSSed． The basic properties were detected such as dissolvability、emulsification、HLB et。the stabilition of hydrolysis were studied．The varies of critical micelle concen廿ation(emc)and surface_tension were investigated in a queons solution with different PH and tempertafion．111e properties of the system of borate surfactant and cationic surfactant have been investigated and parameters of molecular interaction wele ealculaled．The rules about structure and properties of NxB and NxOB were calculated by quantum chemistry． In order to investigate the application,the catalysis as ion liquid and anlistating have been investigated．Firstly,2-Hydroxy-4-octyloxybenzophenone Was synthesized from 2,4-dihydroxybenzophenone and octyl chloride in the presence of N．octyl—diethanolamine borate as ion liquid。and 2-Hydroxv4-mcthyloxybenzo phenone Was synthesized from 2,4·dihydroxybenzophenone and dimeh)，lsulfate in the presence of N·octyl．diethanolamine borate as catalysis．The dynamics property Was discussed，the surface resistance Was measured in PP,and the antistatic mechanism was investigated initially．nle main results ale as follows： 1．Aliphatic acid acylchlorides were synthesized in PCI3 as acylating agent，and the bmmic alkylradical were synthesized in olry HBr．nle affecting factors were discussed． 2．NB、NxB and NxOB were synthesized，ne optimized methods of synthesis Were determined by discussing the factors affecting reactions，their structures were testiffed by F11R、1H．NMR． 3．The property rese
