The model number 1801, 1810, 1809, 1840, 1865 and so on behind stearic acid all mean something

The model number after stearic acid and so on all indicate the type of stearic acid.

In these models, 18 means C18, i.e., the number of carbon atoms contained in the stearic acid molecule is 18. The following number indicates the content of stearic acid, and the higher the number, the higher the content, and the higher the **.

For example, 1801 indicates stearic acid with a C18 content or more, 1810 indicates a stearic acid with a C18 content of 10% or more, and 1865 indicates a stearic acid with a C18 content of 65% or more.

In addition, different models may also indicate different application areas and uses, such as 1865 is commonly used in the manufacture of high-end cosmetics and lubricants.

Stearic acid 1801 and 1840 are very similar in chemical structure, they are both long-chain saturated fatty acids, and both have the molecular formula C18H36O2, but the difference between them is their carbon chain length and three-dimensional configuration.

Stearic acid 1801 usually refers to n-octadecyl stearic acid, that is, stearic acid with a carbon chain length of 18 and no asymmetrical stereoconfiguration. Stearic acid 1840 refers to a mixture of C18 and C20, that is, stearic acid with a carbon chain length of 18 and 20 respectively, which is also a stereo-configuration without asymmetry.

Stearic acid 1801 and 1840 are mainly used as fine chemicals and oleochemical raw materials. Stearic acid 1801 can be used in the synthesis of surfactants, the production of lubricants and greases, and can also be used as a solvent or flexible agent in coatings, paints and other fields. Stearic acid 1840 is mainly used for the synthesis of emulsifiers, the manufacture of washing and distribution agents, lubricants, papermaking auxiliaries, etc.

For subtle differences, the production and use of stearic acid 1801 and 1840 can be slightly different, but overall, the difference between the two types of stearic acid is not very significant. In the actual application process, it can be flexibly selected according to needs. <>

Stearic acid is a long-chain fatty acid that is commonly used in the manufacture of products such as cosmetics, soaps, and lubricants. Stearic acid 1850 and 1860 refer to stearic acid molecules of different lengths, where 1850 indicates that its molecular length is 18 carbon atoms, while 1860 indicates its molecular length of 18 carbon atoms and 1 methyl group.

Although there is only a slight difference between the two in molecular length, their sexual judgment and application are different. Stearic acid 1850 is commonly used in the manufacture of detergents, lubricants, and plastics because it increases the viscosity and consistency of products. On the other hand, stearic acid 1860 is commonly used in the manufacture of cosmetics because it increases the softness and shine of the product.

In addition, stearic acid 1860 is also an excellent emulsifier for crude products, which can help mix immiscible substances.

In conclusion, although there are only minor differences in molecular length between stearic acid 1850 and 1860, their applications and properties are different, and they need to be selected according to actual needs.

Stearic acid 1850 and 1860 are two materials in chemistry. The main difference between them is that they have different carbon chain lengths, stearic acid 1850 contains 18 carbon atoms, and stearic acid 1860 contains 18 carbon atoms and 1 double bond. This makes them different in application.

Stearic acid 1850 is mainly used in the manufacture of lubricants, plastic softeners, surfactants, etc. Stearic acid 1860 is mainly used in the manufacture of vegetable oil substitutes, paints, pigments, etc. In addition, stearic acid 1860 is more active than stearic acid 1850 in the chemical Li Hu reaction, so in some cases, it has an advantage.

18 mainly refers to the C18 stearic acid in stearic acid, which is an important indicator of stearic acid, the general industrial palm oil direct hydrogenation - hydrolysis of stearic acid, C18 content is usually 38-42%, through fractionation, can obtain C18 content of stearic acid, while producing low C18 content of stearic acid (mainly C16), C18 content is usually higher, ** is also higher, and C16 high **low, of course, high purity (> 98%), except.

In addition to palm oil, the raw materials of stearic acid include sheep fat, lard, cottonseed oil, gutter oil, acidified oil and other oils. Usually 800 type stearic acid is produced from tallow leol. Its C18 content is between 60-68%.

1830 1831 1838 1839 and other models, 400 800 and 200 types, are the labels of different manufacturers, 18** series may be based on foreign and imported brands, mainly distinguished by C18 content, but the models of different manufacturers may be the same, but their quality indicators are not necessarily the same, the same is Taike brown, and other manufacturers may be different;

The type is the original domestic standard, mainly based on the iodine value to distinguish, usually the lower the better, corresponding to the iodine value of 2cg g, 4cg g, 8cg g. Most iodine stearate values are now controlled to be less than 1cg g, or even less than.
