Ethyl acetate 16.6 ℃ icing. Of the properties of ethyl acetate, melting point of 16.6 ° C, boiling point 117.9 ° C, relative density 1.0492 (20 / 4 ° C), density than water, refractive index of 1.3716. ethyl acetate has a high freezing point, room temperature is very easy to solidify, as icing. Usually below 16.6 degrees Celsius can be frozen solid, often called glacial acetic acid. So ethyl acetate 16.6 degrees Celsius icing.
