Ethyl acetate is a popular solvent in organic chemistry laboratories. What are the potential health hazards of this solvent? Would you consider dichloromethane more or less hazardous?
Homework Answers
Ethyl acetate --> it irritates eyes, nose and throat. Also can produce headache and as much time is present, this increases nausea nad vomiting . High concentrations will cause toxicity. Prolonged exposure = live r+ kindey problems as well as carcinogenic
dichloroethane --> this is also considered a very flammable + dangereous and even carcinogenic material. Will vaporate readilty. The cnacer risk for dichlorotehane >> ethyl acetate
Therefore, use Ethyl acetate when possible

condensation of ethyl acetate
12. Why is CH3ONa not used in the Claisen condensation of ethyl acetate? a. CH30 is a weaker base than the CH3CH20-which is used. b. CH3O- Nat is more difficult to prepare than CH3CH2O Nat. c. CH3O- would abstract a proton from the ethyl group of the ester. d. Use of CH,O- Na would result in transesterification e. CH,O- Na can be used as well as...

I need help with a 2-part organic chemistry lab. The main topic is esterification of fatty acids. In the reaction, I mix acetic acid, ethanol, and diethyl ether (solvent) together and then add the reagent (H2SO4) to the flask. The final product of this reaction is ethyl acetate. Ethyl acetate is then extracted in a separatory funnel using NaOH. For this reaction, I need help with 2 things. I need help with the overall reaction mechanism, and in identifying the...

The recrystallization technique discusses using a drying agent before recrystallizing out of an organic solvent, however, we omitted the drying step before evaporating off the ethyl acetate. Since we didn't dry this sample, what potential issues might this have caused for analysis of the benzoin sample? Be specific about the effects it would have (if any) on each of the three analysis techniques we used. (4 pts) Melting Point, thin layer chromotography, and gas chromotography
