FOREWORD
This Indian Standard (Fourth Revision) was adopted by the Bureau of Indian Standards, after the draft tinalized
by the Alcohols and Allied Products Sectional Committee had been approved by the Petroleum, Coal and Related
[’roducts Division council.
This standard was first issued in 1950 and subsequently revised in 1966, 1976 and 1986. At the time of tirst
revision, acomparative study ofthe standard with the drafi 1S0 Recommendation No. 656 ‘Sampling and methods
of test for acetone’ was undertaken. A revised scheme of sampling and criteria for conformity, a new procedure
for determination of alcoholic impurities, retlnement in the test for alkalinity and additional requirement for
water content were included in the revised standard. As a result of experience gained through the use of first,
scconct and third revisions and in order to meet the present day requirements of acetone, the fourth revision was
undertaken, In this version requirements of purity and permanganate time have been incorporated using
CC method for verification of purity. Requircinent of residue on evaporation has been modified.
Acctonc is an important commercial solvent and raw material with awide usage inthe chemical, explosives and
lacquer industry. It iscommonly used as asolvent for cellulose acetate; nitrocellulose; celluloid; cellulose ether;
chlorinated rubber; various resins, fats and oils; and as an absorbent for acetylene. Itisbeing increasingly used in
the synthesis of a number of chemicals such as diacetone alcohol, methyl isobutyl ketone, phorone, isophorone,
methyl methocrylate and certain resins, pharmaceuticals and perfumes.
For the purpose of deciding whether a particular requirement of this standard is complied with, the final value,
observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with
IS2: 1960 ‘Rules for rounding off numerical values (revised’. The number of significant places retained in the
rounded off value should be the same as that of the specified value in this standard.
