硬脂酸是自然界广泛存在的一种脂肪酸，几乎所有油脂中都有含量不等的硬脂酸，在动物脂肪中的含量较高。那你知道硬脂酸、软脂酸和油酸的区别是怎样的吗？下面氢氧化钾厂家为您解说。

Stearic acid is a kind of fatty acid widely existing in nature. Almost all oils contain stearic acid with different contents, and the content in animal fat is relatively high. Do you know the difference between stearic acid, palmitic acid and oleic acid? The potassium hydroxide manufacturer will explain it to you.

1、分子式不同

1. Different molecular formulas

硬脂酸：硬脂酸的分子式为CHO。

Stearic acid: The molecular formula of stearic acid is CHO.

软脂酸：软脂酸的分子式为CHO。

Palmitic acid: The molecular formula of palmitic acid is CHO.

油酸：油酸的分子式为CHO。

Oleic acid: The molecular formula of oleic acid is CHO.

2、密度不同

2. Different densities

硬脂酸：硬脂酸的密度为0.9408。

Stearic acid: the density of stearic acid is 0.9408.

软脂酸：软脂酸的密度为0.8527。

Palmitic acid: The density of palmitic acid is 0.8527.

油酸：油酸的密度为0.8910。

Oleic acid: The density of oleic acid is 0.8910.

3、沸点不同

3. Different boiling points

硬脂酸：硬脂酸的沸点为183-184C。

Stearic acid: The boiling point of stearic acid is 183-184C.

软脂酸：软脂酸的沸点为351.5C。

Palmitic acid: The boiling point of palmitic acid is 351.5C.

油酸：油酸的沸点为350-360℃。

Oleic acid: boiling point of oleic acid is 350-360 ℃.

硬脂酸是碳十八酸，软脂酸是碳十六酸，油酸是碳十八含一个双键。

Stearic acid is carbooctadecanoic acid, palmitic acid is carbohexadecanoic acid, and oleic acid is carbooctadecanoic acid with a double bond.

非常大的区别是，硬脂酸和软脂酸的工业成品是固体，而油酸是液体。

The big difference is that the industrial products of stearic acid and palmitic acid are solid, while oleic acid is liquid.

此外您需要了解的是，硬脂酸主要用作润滑剂、抗粘剂、助流剂。特别适宜油类、浸膏类药物的质粒，制成的颗粒具有很好的流动性和可压性。更多相关产品的信息就来我们网站http://www.jinhao360.com咨询吧！

In addition, you need to know that stearic acid is mainly used as a lubricant, anti viscosity agent and flow aid. It is especially suitable for the plasmid of oil and extract drugs, and the particles made have good fluidity and compressibility.
