摘要： Amino azoic dyes having general formula (I) wherein: R1 is linear or branched alkyl having from 6 to 20 carbon atoms; R2 and R3 are independently H, CH3, C2H5, OCH3 or OC2H5; R4 and R5 are independently H, CH3 or C2H5; X is H or OH; and Y is hydrogen or poly-isopropxy chain (IA) wherein n is between 1 and 4. They are used as markers of oil distillation product.

摘要： Novel addition products of hydroxyl-protecting groups (such as isocyanates) with oxyalkylene-substituted intermediates, such as poly(oxyalkylenated) aniline compounds, for the eventual production of substituted, and substantially pure, colorants, particularly diazo and triphenylmethane derivatives, through the reaction of such intermediates with certain reactants are provided. These new colorants exhibit improved wax and/or oil solubility and high purity, particularly due to the inability of certain impurities to deleteriously react with the protected hydroxyl groups of either the intermediate or the colorant during and/or after formation thereof. A method for producing such novel colorants through utilization of these novel substantially pure colorant intermediates is also provided.
