Reaction Conditions:

with Cu(NO₃)₂3H₂O;N-hexadecyl-N,N,N-trimethylammonium bromide;hydrazine hydrate monohydrate;silicon at 220 - 260; under 760.051 Torr; for 1 h;Microwave irradiation;

Steps:

5 Example 5

Weigh 5g silicon powder, 0.25g nano-copper placed in a mortar grind, with 200 mesh sieve,The sieved silica fume - nano copper catalyst mixture into a microwave oven, microwave treatment 3min,Power of 600W; pre-treated silica fume - nano copper catalyst mixture at 10MPa tabletting,40-60 sieve to prepare a spare silica fume - nano copper catalyst mixture.Methanol after vaporization (gasification temperature of 200 ° C) into the step loaded with the silica fume - nano-copper catalyst (2)Agent mixture in a fixed bed reactor (20 cm in length, 0.5 cm in inner diameter) for the gas phase catalytic reaction,The loading of catalyst was 4g, the flow rate of sample was 8mL / h, the flow rate of carrier gas was 20ml / min,The reaction is carried out at atmospheric pressure, the reaction temperature is 220-260 ° C, continuous sampling at a given temperature for 1 hour,The product was condensed in an ice-water bath and analyzed by gas chromatography. The results of the catalytic reaction are shown in the following table:
1.93 g of cupric nitrate trihydrate and 0.193 g of CTAB were dissolved in 40 ml of anhydrous ethanol,Ultrasonic 30min all dissolved to form a mixed solution, when the mixture warmed to 60 ,Dropping 1.5mol / L NaOH ethanol solution dropwise to adjust the pH value of the mixture to 8;Then a solution of hydrazine hydrate in ethanol (6 ml of 85% hydrazine hydrate / 50 ml of absolute ethanol) was added dropwise,And the reaction was stirred under magnetic 2h, after the reaction was cooled to 30 ° C to prepare a backup nano copper.
