반응 단계
A suspension of 37.8 parts of dimethyl 3,6-dihydro-2,5-dianilinoterephthalate in 200 parts of ®Dowtherm A is added dropwise to 150 parts of boiling ®Dowtherm A. The mixture is then kept at the boil for a further 90 minutes. Approx. 100 parts of the solvent are then distilled off and 254 parts of a 10% strength solution of iodine in ®Dowtherm A are then added dropwise. Working up is effected as described earlier in the text under "Method A". 27.7 parts of quinacridone in the γ-crystal phase are obtained, which corresponds to a yield of 89% of theory (relative to dimethyl 3,6-dihydro-2,5-dianilinoterephthalate).
