【Abstract】 In this paper,the convenient condition ofanalys is is expounded,when we usetitanometry to determine the content of diazonium salt in semifinished product:wetake in the order of operation that the sample is put in the titanium trichloridesolution slowly;the quantity of titanium trichloride is in excess of 200% or so;the time of reaction is 20 minute.Using this method,the content of 3-methyl-4-pyrrolidinyl benzene diazonium zine chloride,a new diazo light sensitive agent,is determined accuratly.It is 98.78%.更多还原
