Beschreibung
Zusammenfassung:	FIELD: oil production, oil refinery and petrochemical industries, particularly for hydrogen sulfide and mercaptan neutralization in hydrocarbon medium with the use of chemical neutralization agents. ^ SUBSTANCE: hydrogen sulfide and mercaptan neutralizing agent comprises 30-58% by weight of formalin, alkali metal, preferably sodium, hydroxide or carbonate in amount of 0.1-3% by weight, hexamethylenetetramine in amount of 15-25% by weight, remainder is tertiary alkamine, preferably triethanolamine and/or methyldethanolamine. Neutralizing agent in accordance with the second embodiment additionally includes bactericide composition. ^ EFFECT: increased neutralizing agent efficiency, enhanced manufacturability (low solidification temperature) and reactivity, provision of high hydrocarbon medium (oil, oil product and gaseous hydrocarbon) cleaning of hydrogen sulfide and light-weight mercaptans at room and increased temperatures (of 10-90°C and higher), improved bactericidal activity and corrosion inhibiting effect in hydrogen sulfide mediums, possibility of neutralizing agent usage as bactericide and corrosion inhibitor in oil-field media. ^ 7 cl, 15 ex, 1 tbl
