we prepared ethyl acetate in our lab.afterwards we washed it with water then with cacl2(aq) then with cacl2 granules.i know that the anhydrous granules eliminates water,but how about in the case of using aqueous calcium chloride

If I remember correctly it is there to wash away any un-reacted reactants and also "neutralize" them. So if your proportions are not exact it will react away either of the reactants left since both would also be soluble in the ethyl acetate.

the ethanol is dehydrogenated over a dehydrogenating catalyst in the presence of hydrogen.The liquifiable products present in the resulting reaction product are hydrogenated over a suitable catalyst A two step distillation process is used to purify the hydrogenated product.Afirst distillate of ethyl acetate,ethanol and water produced in the first distillation zone is redistilled in the second distillation zone therby producing a product from about 99.8mol% to about 99.95% ethyl acetate and an overhead second distillate. CH3COOH + HOCH2CH3-----------CH3COOCH2CH3 + H2O
