Abstract:
Anionic surfactants have a formula: RfSO2N(H)—CH2CH(CH3)OH; or RfSO2N(H)—CH2CH2O)xH, where x is an integer from 2-6. Rf is a fluoroalkyl group having 3 to 8 carbon atoms. Neutral surfactants having a formula: (a) Rf—SO2N[CH2CH(CH3)OH]2; (b) RfSO2N[CH2CH(CH3)OH][(CH2CH2O)nH], where n is an integer from 1-6; (c) RfSO2N(R)[(CH2CH2O)pH], where p is an integer from 2-6, and R is an alkyl group having 1 to 4 carbon atoms; or (d) RfSO2N[(CH2CH2O)qH][(CH2CH2O)mH], where q is an integer from 1-6 and m is an integer from 3-6. Rf is a fluoroalkyl group having 3 to 8 carbon atoms.
