Abstract:
     A high-speed process for synthesizing the nano-class Ti-Si molecular sieve catalyst includes preparing ammonium tetrapropyl bromide, exchanging with strong alkaline anionic resin, concentrating to obtain the aqueous solution of ammonium tetra propyl hydroxide as template agent, proportionally mixing it with ethyl ortho silicate and tetrabutyl titanate in hydrothermal crystallizing system, hydrolysis, mixing, reaction for 3-6 hr to remove alcohol, and crystallizing for 12-44 hr. Its advantages are high speed, less consumption of template agent and low cost.
