Today, dearomatized hydrocarbon solvents
are widely used in manufacturing, cosmetic, and fast moving consumer
goods sectors due to onset of stringent environmental norms.
Conventionally, the solvency of such solvents is measured in terms
of Kauri Butanol (KB) value. The measurement of KB value, as per
ASTM-D1133, is costly, time consuming, and tedious process. To
overcome such limitations, the present study reports, an innovative
method using Fourier Transform-Near Infra-Red (FT-NIR) spectroscopy
based rapid and reliable technique for estimation of solvency power.
Partial least squares regression was used to develop calibration and
prediction of KB value by the use of TQ Analyst 8 software
associated with FT-NIR analyzer. This method is fast, safe,
reliable, nondestructive, and inexpensive contrary to conventional
procedures. The results obtained based on developed method are found
to be in good agreement with those reported based on standard test
method, that is, ASTM-D1133. |
