Determining the drop point of tar oil by automatic drop point determination technology (CAT#: STEM-PPA-0191-LJX)

Introduction

Coal tar is a pungent black or black brown viscous liquid produced by the distillation of coal. Coal tar is generally used as a raw material for processing and refining to make a variety of chemical products, and can also be directly used, such as as an industrial briquette, coke and coal-based activated carbon binder ingredients, but also can be used as fuel oil, blast furnace injection fuel and wood anticorrosive oil and burning carbon black raw materials.

Principle

During the test, the cup containing the sample is placed on the support, and the furnace is installed on the outside of it. The expected drop point temperature of the sample is set through the instrument keyboard, and the temperature is raised according to the preset heating program. The photodetector automatically records the temperature at which the first drop of sample is dropped from the mouth of the cup, which is the drop point of the sample.

Applications

For drop point determination of non-crystalline materials such as synthetic and natural products

Procedure

1. Place the sample in the cup and put it on the support in the furnace
2. Start the instrument program to heat up
3. The instrument automatically records the temperature at which the first drop of sample drops from the mouth of the cup, that is, the drop point

Materials

• Sample Type:
Tar oil

Notes

The experiment should be repeated three times, and the average value should be taken to ensure the accuracy of the results.
