Preparation of crude acetanilide The purification of chloroform 15. Preparation of crude acetylsalicylic acid Preparation of crude bromoethane The preparation of ethyl crude acetate The preparation of acetaminobenzene sulfonyl chloride The preparation of diphenylacetone The organic chemistry experiment is one The name Experiment name: the preparation of ethyl acetate Principle: Ch3, ch3, ch3, CH2CH3 plus H2O Experimental steps: (80 points) In 250 ml three-necked flask to mix 15 ml 15 ml concentrated sulfuric acid, anhydrous ethanol and in the three neck flask containing a thermometer, a dropping funnel and a glass tube, the glass bending tube even has been shaped condenser pipe; Condenser pipe through a tail pipe with triangle flask are interlinked, with electric heating, the temperature rises to 110 ~ 1200 c when start using drip funnel into 17.6 mL a mixture of ethanol and 17.3 mL glacial acetic acid. When it is finished, it will continue to heat until the liquid distillate is no longer in the 1300C, and the product is returned to the recycling bottle. 3, draw the experimental setup (10 points) What impurities may be in the product that is made? How do you get rid of it? (10) Note: ethyl acetate b.p = 77.10 C, d = 0.901 Organic chemistry experiment 2 The name Laboratory name: the preparation of the crude para-sulfonate Principle: - NH2 + - H2SO4 NH2 - SO3H + H2O Experimental steps: (75) In 250 ml three neck, add 10 ml
