title: [Analytical control over 4,4'-bis-maleinimide diphenylmethane].
abstract: The authors studied detection of 4,4-bis-maleinimid-diphenylmethane in aethylacetate by means of fluorimetry and direct spectrophotometry. Detection of the individual substance is highly sensitive, reproducible and express. Limit of 4,4-bis-maleinimid-diphenylmethane detection through spectrophotometry is 0.1 mg/ml and that through fluorimetry is 0.03 mg/ml. Studies covered interference of the synthesis' initial components on 4,4-bis-maleinimid-diphenylmethane detection in aethylacetate. Multicomponent mixtures of bis-maleinimids were analyzed according to Firordt additivity rule. The techniques elaborated are useful for sanitary and hygienic control over 4,4-bis-maleinimid-diphenylmethane in the air of workplace.
