Soil bacteria have been grown with quinoline as the sole carbon source Grant and Al-Najjar While the isolation procedure may from dye to dye, a typical procedure would be to neutralize the excess phthalic anhydride as acid with sodium hydroxide or sodium carbonate and then to salt the dye out of solution and to isolate the dye by filtration. Example 3 Following the general processes described in Examples 1 and 2, quinaldine derivatives were prepared by starting with the following aromatic amino sulfonic acids: When the 2-methylquinolinesulfon-ic acids thus obobtained are condensed with phthalic anhydride according to procedures described below, one obtains greenyellow dyes for paper which exhibit excellent strength and brilliance when applied to bleached sulfite pulp. The precipitated dye is filtered off and half of the filter cake is dried.
