Preparation method of double-amino-terminated silyl ether compound, and double-amino-terminated silyl ether compound

The invention discloses a preparation method of a double-amino-terminated silyl ether compound, and the double-amino-terminated silyl ether compound. According to the preparation method, an available chlorosilyl ether compound or silyl ether compound is used as a starting material, the starting material reacts with an alkenyl Grignard reagent to construct a C-Si bond, and catalysis of a noble metal catalyst is not needed, so the method has the advantages of low production cost, mild and controllable reaction conditions, safety, environmental protection, high efficiency and suitability for large-scale industrial production. In addition, the preparation method is especially suitable for preparing the double-amino-terminated silyl ether compound containing a large steric hindrance aryl group and a heterocyclic ring substituent group with an electron withdrawing or electron donating effect, and the target product can be obtained with high yield.

PROCESSES FOR MAKING POLYSILOXAZANES AND USING SAME FOR PRODUCING AMINO-FUNCTIONAL POLYORGANOSILOXANES

A process for preparing a cyclic polysiloxazane is disclosed. The cyclic polysiloxazane may optionally be converted to an a-alkoxy-ou-amino-functional polysiloxane. The cyclic polysiloxazane or the a-alkoxy-oo-amino-functional polysiloxane, may be used as

A double-end amino (poly) method for the preparation of

A double-end amino (poly) silicone preparation method, which is characterized in that: the olefin-based primary amine and aromatic or aliphatic formed in ice of phthalic anhydride in acetic acid solvent, for 0 o C-10 o C reaction 1-3h, reflux 3-6h, water, precipitated N-olefin-imide; the molar ratio of 1 : 2.0-5.0 of siloxane and including hydrogen base N-olefin-imide, the aromatic hydrocarbon or alcohol, ether solvent, the presence of a platinum catalyst, for 30 o C-120 o C reaction 3-10h, cooling to room temperature, filter, pressure reducing evaporate the solvent, get [...] imide silicone; the double-phthalimide siloxane dissolved in organic solvent, under the acid catalysis and D 3 or D 4 for 30 o C-100 o C reaction to obtain [...] imide silicone; the double-phthalimide (poly) silicone using ethanol as the solvent, by adding hydrazine hydrate in 60 o C-80 o C reaction 5-15h, filter, pressure reducing evaporate solvent. The process of the invention is simple, normal pressure reaction, non-corrosive material, with little investment; all yield and purity of the product is very high; the solvent can be recycled, the production cost is low, no environmental pollution; by-product of phthalic hydrazide also can be widely applied.
