In order to encourage new investment and capacity addition in the chemicals and petrochemicals sector, he proposed to reduce the BCD on reformate, ethane, propane, ethylene, propylene, butadiene and ortho-xylene
, methyl alcohol and denatured ethyl alcohol, and crude naphthalene.
More promising economically, however, are G'100 blends that include various types of xenols, including para-, meta- or ortho-xylene
The upgrade in the ratings takes into account the improvement in the financial performance during financial 2010 aided by a sustained recovery in the spread between Phthalic Anhydride (PAN) and Ortho-Xylene
