摘要
The composition of a gas or gas stream containing AlCl3 in a chemical reactor is measured by removing AlCl3 from the gas and analyzing the gas by gas chromatography or spectroscopy. Chlorosilanes may be prepared in a fluidized bed reactor having a reactor height H0, in which supplied HCl reacts with silicon, wherein a temperature profile in the fluidized bed reactor is greater than S1(H/H0)=(a1−b1)*(1/(1+exp(−c1((H/H0)−d1))))+b1 and less than S2(H/H0)=(a2−b2)*(1/(1+exp(−c2((H/H0)−d2))))+b2, where a1=100° C., a2=300° C., b1=300° C., b2=400° C., c1=50, c2=20, d1=0.2, and d2=0.8.
