Preparation method for silane peroxide coupling agent

The invention provides a preparation method for a silane peroxide coupling agent. The catalyst titanium tetrachloride is initiatively added into reaction raw materials and the dosing ratio of raw materials is adjusted, so that the dosage of 3-gamma-chloropropyl trimethoxysilane is increased while the dosage of sodium tert-butanol peroxide is reduced; the mole ratio of sodium tert-butanol peroxideto 3-gamma-chloropropyl trimethoxysilane to titanium tetrachloride is kept within the scope of (0.8-1.0):2:(0.05-0.1), so that the yield of the product silane peroxide coupling agent of the inventioncan be increased; by calculation, the yield of the silane peroxide coupling agent prepared according to the preparation method for the silane peroxide coupling agent provided by the invention is 92-98%; in addition, the dosing ratio of raw materials is adjusted in the invention, so that the after-treatment process of the product silane peroxide coupling agent is simplified, the product loss is avoided and the increasing of product yield is benefited.

An over-oxidation of the silane coupling agent preparation method

The invention relates to a peroxide silane coupling agent and its preparation method. Technical problems of single function, and needing of a two step reaction of cladding and polymerization in the use of inorganic particle modified polymers of present silane coupling agents are solved. The peroxide silane coupling agent is a gamma-t-butylperoxypropyltrimethoxy silane coupling agent, and the structural formula of the peroxide silane coupling agent is shown in the specification. The preparation method comprises the following steps: 1, preparing t-butyl hydroperoxide sodium; 2, reacting t-butyl hydroperoxide sodium with 3-chloropropyltrimethoxysilane; 3, washing to remove t-butyl hydroperoxide sodium, sodium chloride and toluene in the obtained product; and 4, extracting by using an n-hexane and ethyl acetate mixed solution as an extractant, carrying out low temperature storage, filtering, and carrying out rotary evaporation to obtain the peroxide silane coupling agent. One end of the coupling agent is a hydrolysable methoxy group, and the other end of the coupling agent is a peroxide group capable of initializing polymerization, so the coupling agent can be used in an inorganic particle surface modification and polymer grafting combined reaction.

The novel peroxides Me3SiOSO2OOR (3; R = n-C3H7, n-C4H9, n-C5H11), Na+-OSO2OOR (5; R = n-C3H7, n-C4H9), and HOSO2OOR (6; R = n-C3H7, n-C4H9) are obtained by insertion of SO3 in Me3SiOOR, NaOOR, and HOOR respectively (temperature below -20 deg C, solvent CH2Cl2).The solid compounds 5 are stable up to 40-50 deg C, the liquids 3 and 6 deflagrate at ca. -10 deg C.Hydrolysis of the sulfonyl peroxides generates HOOR in each case.Thermolysis of 3 affords the corresponding aldehydes by heterolysis of the (O-O)-bond.In CH2Cl2 at room temperature, Me3SiOSO2OOSiMe3 (1) undergoes a slow nucleophilic 1,2-rearrangement, forming the isomer Me3SiOSO2OSi(OMe)Me2 (7).The constitution of 7 is confirmed by chemical evidence, e. g. hydrolytic and thermal degradation.Thermolysis of Me3SiOSO2OOSO2OSiMe3 (2) at room temperature in CH2Cl2 occurs by a rather rapid free radical pathway, the solvent being attacked by H and/or Cl abstraction (main products: HCl, CO, ClSO2OSiMe3, Me3SiOSO2OSiMe3).The new trimethylsilyl(n-alkyl)-peroxides Me3SiOOR with R = n-C3H7, n-C4H9, and C5H11 were prepared and characterised.
