  A tert-amine which contains an acid-activated color body precursor is treated to prevent it or a derivative thereof, e.g., an amine oxide, betaine, or quaternary ammonium compound, from turning pink when exposed to acidic conditions by contacting it at an effective temperature with a discoloration inhibitor which is (1) an inorganic sulfite selected from alkali metal sulfites and bisulfites, (2) an alkanal containing at least two carbons, (3) an acetylalkylcarbinol, (4) an amido compound which contains a -CO.NH- group, (5) ammonium carbonate, (6) a dialkylacetal, or (7) ascorbic acid. Ambient temperatures are satisfactory for the treatments with the other discoloration inhibitors, but temperatures above 100°C are required when the discoloration inhibitor is an inorganic sulfite.

  对含有酸活化色体前体的叔胺进行处理，以防止其或其衍生物（如氧化胺、甜菜碱或季铵化 合物）在酸性条件下变成粉红色、(1)选自碱金属亚硫酸盐和亚硫酸氢盐的无机亚硫酸盐；(2)至少含两个碳原子的烷醛；(3)乙酰烷基甲醇；(4)含 -CO.NH-基团的氨基化合物；(5) 碳酸铵；(6) 二烷基缩醛；或 (7) 抗坏血酸。使用其他变色抑制剂进行处理时，环境温度是令人满意的，但当变色抑制剂是无机亚硫酸盐时，则需要 100°C 以上的温度。
