USERS REPORT BIG DIVIDENDS FROM HIGH-PURITY SUN AROMATICS

Processing easier, yields higher; all at no increase in price!

The higher purity of Sun's aromatics is already paying big dividends. Several Sun customers are reporting higher yields. Others claim they are getting better, more uniform products. One company reports they have been able to eliminate com­pletely a purification step in processing —and still maintain the quality of their end product. And all these plants are getting these dividend-producing, higher-

purity products at no increase in price! The high purity of Sun's Benzene,

Toluene and Xylene is no accident—Sun spent $15 million on a plant specifically designed to produce quality products. Rigid controls and constant testing assure you of the same uniform, high-purity products month in and month out.

TYPICAL TESTS

BROMINE INDEX. The extreme sensitivity of this new test tells Sun Engineers when filters need changing—long be­fore filter deterioration can affect the quality of Sun's aromatics. It assures you of both uniformity and high purity.

DISTILLATION RANGE. Every sample tested must fall within the narrow boiling range specified in ASTM Method D-850. Typical analyses show that Sun's aromatics usually have a much narrower boiling range than is re­quired to pass this test.

PARAFFIN TEST. Sun Toluene is guar­anteed to contain less than 0.5% paraffins—substantially below the ASTM maximum of 1.5%. Samples normally contain no measurable par­affin whatever.
