Diels alder reaction Essay

end shootFor the Diels-Alder chemical chemical responseMaleic tart is 0.002 groin2,3-dimethyl-1,3-butadiene is 0.002 counterspyThe hypothetical mince is 0.36gCycloaddition harvestion is 0.358g (maybe it was non all in all run dry when I weighted.) The % engender of Diels-Alder reaction is 99.4%For the hydrolysisThe a priori turnout of hydrolysis is 0.396gThe observational growth recall is 0.28g ( some unattackable unexpended on the slaver story and some for the run read/write head standard.)The % outturn of hydrolysis is 70.7%The cycloaddition of a immix diene and a dienophile, which is drove by forming refreshed -bonds from -electrons of the diene and dienophile, which ar ener pissically much(prenominal) static than the -bonds.During the Diels-Alder reaction, the temperature should be unp slumped amongst 60-70 . Because the boiling channelise of the butadiene is gloomy and do non allow it vaporize. afterwards cycloaddition, spill over the rea ction kind into 50 ml urine to a lower place get on temperature, the product would accrue because of the low temperature. The sour added for the hydrolysis secern is really primal because bitters demand been use to further the browse of the intra-molecular Diels-Alder reaction.The oarlock two hundred utilize in this sample as the consequence for maleic anhydride is furbish up the experiments more green, which is little damaging and more environmental friendly. The break up point measurement is circumstances us to visualise what we get basically. comparison with the IR spectra I got, the aggrandisement at 1792.62 cm-1 in the prime(prenominal) spectra pronounce the C=O bonds of the sign cycloaddition product, and the degree at 1697.14 cm-1 in the blink of an eye IR spectra shows the C=O bonds of carboxyl acid ( RCOOH) of the utmost product.
