Abstract : This patent application deals with acetals of the formulas CHCl2CH(OR)2, CCl3CH(OR)2, CHF2CH(OR)2, CF3CH(OR)2, RO2CCH(OR)2, and (RO)2HCCH(OR)2 wherein R can be -CH2CYZ(NO2), -CH2CH2CYZ(NO2), -CH2C(NO2)2CH3, -CH2C(NO2)2CYZ(NO2), -CH2C(NO2)2CH2CYZ(NO2) or -CH2C(NO2)2C(NO2)2CYZ(NO2) wherein Y and Z vary independently and can be Cl, F or NO2. These acetals are produced by contacting a negatively substituted aldehyde such as CHCl2CHO, CCl3CHO, CHF2CHO, CF3CHO, HO2CCHO, or OHCCHO with negatively substitute alcohol of the formula ROH wherein R is as defined above. Either FSO3H, ClSO3H, or CHF2SO3H, or CF3SO3H is used to catalyze the condensation. The acetals of this invention are useful as explosives and composite propellants.
