One of the main products in the process is mainly petroleum fractions at ~°C, with a relative molecular mass of ~ and a density usually... Paraffin wax has no definite molecular formula. The general molecular formula is +, and the number of carbon atoms in the formula is ~3. Paraffin wax has excellent properties such as waterproof, moisture-proof, anti-microbial and anti-decomposition
and is widely used in paper making, daily chemicals, food, agriculture, rubber, plastic packaging, candle making, hot melt adhesive, etc.
However, in daily life and industrial applications, especially in candle manufacturing, paraffin wax has shortcomings such as low strength, low melting point, and easy softening in summer. The current solution is to add stearic acid to paraffin wax to improve its strength. By adding stearic acid, not only can the strength and softening resistance of paraffin wax be improved, but the flame of paraffin wax can be bright when burning, with almost no black smoke and no air pollution. However, after adding stearic acid to paraffin wax, no one has done systematic research on the influence and regular changes on the melting point, strength and other properties of the entire system.
To this end, this article studied the melting point and compressive strength characteristics of the paraffin-stearic acid mixed melt system in the range of paraffin mass fraction ~, and used infrared absorption spectroscopy to analyze its mechanism, which has a great impact on the application and performance of paraffin. Improvements are beneficial.
Experimental part
The paraffin wax used in the experiment is fully refined paraffin wax, which is a translucent white block object with a melting point of .℃. Stearic acid is produced by China Petroleum & Chemical Corporation (3() Company) in the form of white flakes. Object, melting point.℃, produced by. The experimental samples were designed with experimental points based on the mass ratios of paraffin and stearic acid::::::,3,::::::::
.
The preparation method of the paraffin-stearic acid mixed melt system sample is: weigh the paraffin according to a certain proportion, put it into a beaker, and heat it until the paraffin just melts
Weigh the stearic acid according to a certain proportion, and add Add it to the melted paraffin
() Control the temperature of the paraffin below ℃. After the stearic acid is fully melted, stir continuously with a glass rod to make the two fully mixed
Cool naturally. That is, the experimental sample is obtained. Use a digital melting point meter to measure the melting point of the sample.
The specific method is: crush the cooled waxy material, and fill the capillary tube with each sample at one time. The linear heating rate of the melting point instrument is uniformly set at ℃, and the starting temperature is ~℃ lower than the melting point.
Effect of stearic acid on the melting point and mechanical properties of paraffin
Measure its compressive strength. The specific method is: prepare the wax material into a cylinder, and the diameter of the bottom surface of the cylinder is ., high. Use sandpaper to polish the upper and lower surfaces of the cylinder smooth and parallel, and place it on the testing machine to measure the strength. An infrared absorption spectrum analyzer was used to conduct infrared absorption spectrum analysis on the above samples. Since the sample has good transparency after melting, the sample preparation method uses the solution method. The specific method is: heat the sample to melt it, and put the melted sample into the sample pool for infrared absorption spectrum analysis.
