| titleOfInvention | Standard materials and methods for instrumental measurement for ASTM color of petroleum products using said standard materials |
| abstract | A set of standard materials, which comprises at least two kinds of standard materials, for calibration of a photoelectric colorimeter used for the instrumental measurement of petroleum products for their ASTM color, comprising at least two kinds of standard materials each of which is a mixed solution having a color corresponding to an ASTM color and comprises (a) at least five members selected from the group consisting of seven specific colorants such as 3-methyl-1-phenyl-4-(phenylazo)-pyrazol-5-ol, 1-(phenylazo)-2-naphthalenol and 1-[[4-[(dimethylphenyl)azo]dimethylphenyl]azo]-2-naphthalenol, (b) 1-phenyl-1-xylylethane as a solvent for said colorants, and (c) dodecane as a diluent; and a method for instrumental measurement of petroleum products for their ASTM color by a photoelectric colorimeter, which comprises calibrating the photoelectric colorimeter by the use of said at least two kinds of standard materials. |
