Abstract

This specification covers solvents based on stabilized normal-propyl bromide (nPB) for use in vapor degreasing. The standard also includes a separate specification for technicalgraden-propyl bromide. Blends and azeotropic mixtures of stabilized nPB for vapor-degreasing shall be blended from nPB meeting the specification for technical-grade nPB. Vapor-degreasing solvents based on stabilized normalpropyl bromide shall conform to the requirements of different properties such as boiling point, acidity, water content, appearance, color, free halogen, nonvolatile residue, acid acceptance, and aluminum corrosion at reflux. Blends and azeotropic mixtures of stabilized nPB with other materials for use in vapor degreasing shall be prepared from technical-grade nPB which shall conform also to requirements of different properties such as: specific gravity, boiling point, acidity, water content, appearance, color, free halogen, nonvolatile residue, normal-propyl bromide content, and iso-propyl bromide content.

1. Scope

1.1 This standard covers solvents based on stabilized normal -propyl bromide ( n PB) for use in vapor degreasing. The standard also includes a separate specification for technical-grade n -propyl bromide.

1.2 Blends and azeotropic mixtures of stabilized n PB for vapor-degreasing shall be blended from n PB meeting the specification for technical-grade n PB.

Note 1Practices D3844 and D4276 and MNL2 provide additional important information on vapor degreasing and solvent properties.
