Document Type and Number:

Japanese Patent JPH03150380

Kind Code:

A

Abstract:

PURPOSE: To prevent the corrosion of a petroleum oil refining apparatus or corrosion by acids and the harmful effect of neutralized salts in a petrochemical process by incorporating amines each having a prescribed base dissociation constant and a prescribed m.p. of formed hydrochloride.

CONSTITUTION: This neutralizing agent for petroleum oil refining and a petrochemical process contains amines (n-propanolamine) each having ≥2.5×10-4 base dissociation constant (Kb) at 25-100°C and ≤80°C m.p. of formed hydrochloride. This neutralizing agent ensures very low corrosiveness for hydrochlorides formed by neutralization and prevents corrosion by acids and the harmful effect of neutralized salts in a petrochemical process.
