Product Description

Item : Automatic TAN/TBN Titrator 
Model: PT-HK-1060A

1. Introduction
The alkalinity value of petroleum represents the standard for the content of alkaline substances in petroleum, usually expressed in mgKOH / g, which represents the neutralization capacity of petroleum. Diesel engines, especially ships, often mix sulfur-containing heavy oil fuel oil and diesel engine oil in the engine, causing the engine to generate acidic substances during operation. The significance of the existence of a base number is to neutralize the acidic substances and prevent equipment corrosion. For metalworking fluids, many petroleum additives can easily fail or deteriorate in an acidic environment. A certain alkali value can ensure the activity of additives in petroleum. Determining the degradation of petroleum additives in lubricating oil by determining the basic components in petroleum by means of acid-base titration can determine the necessary practical waste limit.

2. Instruments and reagents
2.1 Instrument
PT-HK-1060A Automatic Potentiometric Titrator, Hamilton's pH Nonaqueous Composite Electrode, 10mL Burette Unit
2.2 Reagents
Sodium perchlorate electrolyte (saturated solution of sodium perchlorate in glacial acetic acid), titration solvent (mixed with 50 mL of glacial acetic acid and 100 mL of chlorobenzene), perchloric acid glacial acetic acid solution (0.1mol / L)

3. Experimental methods
3.1 Experimental steps
Electrode preparation: Fill the pH non-aqueous composite electrode with sodium perchlorate electrolyte.
Approximately 2.5 g of petroleum is weighed and placed in a titration cup. First add 40mL of chlorobenzene and stir the solution with a stirrer on a potentiometer until the sample is completely dissolved. An additional 20 mL of glacial acetic acid was added. After mixing, titrate to the end point with perchloric glacial acetic acid solution.
