To determine the acid or base number, the sample is dissolved in a mixture of toluene and isopropyl alcohol
containing a small amount of water, and the resulting singlephase solution is titrated at room temperature with standard alcoholic base or alcoholic acid solution, respectively, to the end point indicated by the color change of the added p-naphtholbenzein solution (orange in acid and green-brown in base). To determine the strong acid number, a separate portion of the sample is extracted with hot water and the aqueous extract is titrated with potassium hydroxide solution, using methyl orange as an indicator

ASTM D974 Acid And Base Number By Color Indicator Titration

KN-1060Z Automated TAN & TBN Titrator

Overview

This titrator covers the determination of acidic or basic constituents (Note 1) in petroleum products2 and lubricants soluble or nearly soluble in mixtures of toluene and isopropyl alcohol. It is applicable for the determination of acids or bases whose dissociation constants in water are larger than 10−9; extremely weak acids or bases whose dissociation constants are smaller than 10−9 do not interfere. Salts react if their hydrolysis constants are larger than 10−9.


Features

  1. Unique built-in dosing unit to avoid the harmless chemical leak

  2. Multiple self-checking function to avoid mis-operating

  3. Flexible application edit functions, operator can store the dedicated titration mode to the test and adopt this mode next time by one click

  4. RS232/USB port, with networked CAN but communication functions.

  5. Very easy to use - intuitive keypad and function guide display

  6. Programmable – TAN,TBN software built-in

  7. Results expressed in mg KOH/g

  8. Connects to external pc keyboard for easy text and sample information data entry

  9. Connects to different types printers, pc and balances

  10. Data Logger – automatic data storage of last 55 analysis results

  11. Hamilton electrode ,model number: 238060 FLUSHTRODE made in Swiss
