The density of propionic acid
Propionic acid is unique to all things. The study of its density is related to all ends of engineering and technology. In the past, the Fang family wanted to understand its nature, so they took propionic acid and measured it with a gauge.

At the beginning, clean its utensils so that they are clean and unstained. Next, inject propionic acid into it, observe its shape and state. Then, measure its weight and measure its product in degrees. According to its weight and product, it is calculated according to the technique.

The method of calculation is to divide the product by weight, and the obtained number is the value of the density. However, there is a need in the meantime, the accuracy of the utensils and the accuracy of the quantity are all related to the accuracy of the obtained number. If there is a slight flaw in the utensil, and the amount is slightly different, the number will be different.

Ancient workers relied on this to make things. In the industry of dyeing and weaving, know the density of malonic acid, which can be used to match it with other agents, so that the color is uniform and the quality is good. In the work of making utensil, know its density, and can be used to make the utensil firm and suitable.

Later generations also inherited this technique, adding new techniques, the more refined the research, the more widely used it. The study of the density of malonic acid, in both workmanship and technology, is the essence and cannot be ignored.
