ETHYL SULFATE synthesis

[jmarjorie]

Dear All,

 

In the manufacture of Ethyl Sulfate, CH3CH2-O-SO2OH, does it matter if Ethanol is added to Conc. Sulfuric acid or vice versa, (slowly with stirring ) and if the addition temp is about 25 deg C ?

During the hydration of Ethyl Sulfate, does it matter if Ethyl Sulfate is added to excess water or vice versa ( slowly with stirring ) at the addition temp of 25 deg C ?

Can the Conc Sulfuric acid be regenerated by boiling off the water present ?

Thanks in advance,

jmarjorie

add acid to Water, never Water to Acid, the same applies with alcohol.

if there`s any local heating you`ll get Diethyl ether in your mix, and with water possibly a steam explosion
