METHOD FOR THE DETERMINATION OF AN ACID OR A BASE IN A NON-AQUEOUS LIQUID |
摘要 |
A chemical analysis method for the determination of a base (or an acid) in a non-aqueous liquid (such as a polyol) which method can be automated and placed on-line in a chemical production facility. The instant invention includes two steps. The first step is to mix an acid-base indicator (for example, bromocresol green) with the non-aqueous liquid to produce a colored reaction product between the base or acid and the acid-base indicator. The second step is to determine the intensity of the color of the colored product. |
