Identification:
(1) To about 0.5g, test tube , add acetyl chloride 3ml, slowly dropping pyridine 0.5ml, with
Dropwise with shaking , the reaction is completed once , pay attention to the solution was transferred to another tube , with ice -cooling, the precipitated crystals were filtered ,
After washing with ether 10ml , removal test tube, add ether 15ml, set a warm water bath heated to dissolve , hot dip take the ether
Liquid vaporized ether to give white crystals ( recrystallized again when necessary, 1 ) , after drying , determined by law ( Appendix Ⅵ C),
A melting point of 120 ~ 125 ℃.
(2) to take this product a saturated aqueous solution 1ml, add ferric chloride solution and sodium hydroxide solution each 0.5ml, which generates
