The physicochemical properties of butyl acetate, a substance that butyl acetate cannot dissolve

Butyl acetate is a mixed solvent containing organic solubilizers, which can dissolve some organic matter, but not the following substances:

1.Cellulose acetate: Butyl acetate dissolves cellulose acetate but not other cellulose.

2.Rubber: Butyl acetate can dissolve some rubber, but not others, such as nitrile rubber.

3.Metals: Celvobutyl acetate cannot dissolve metals such as copper, iron, aluminum, etc.

4.Certain chemicals: Some chemicals can cause a decrease in the solubility of butyl acetate, such as some organophosphorus compounds, phenolic compounds, etc.

It is important to note that the above substances are just some common examples, and not all of them are insoluble butyl acetate.

Butyl acetate is a common organic solvent that can usually dissolve many organic compounds, but it is not suitable for dissolving some substances that are insoluble in water and have low solvent polarity, such as some polymer compounds, inorganic substances and some natural substances. The first lead is good.

Here are some substances that are not easily soluble in butyl acetate:

some polymer compounds, such as polyethylene, polypropylene, etc.;

cellulose and other natural polymer compounds;

some inorganic substances, such as oxides, salts, etc.;

Certain natural substances, such as fatty substances, resins, essential oils, etc.

It should be noted that when using butyl acetate for dissolution, it must be selected according to the nature of the lead compound. For substances that are unclear whether they can be dissolved by butyl acetate, it is best to test small samples before the experiment to avoid accidents.

Butyl acetate is an organic compound nucleus, which is mainly used as a solvent. Butyl acetate can dissolve many organic substances, but it cannot dissolve some inorganic substances and polymer celery compounds, such as:

1.metals, metal oxides and metal salts and other inorganic compounds;

2.polymers, such as polyethylene, polypropylene, polystyrene, etc.;

3.Impurities or certain other organic compounds, such as aromatic hydrocarbon compounds, etc.

Butyl acetate can dissolve many organic substances at room temperature, but cannot dissolve some inorganic cover substances such as sodium chloride (NaCl) and sodium thiocalarate (Na?).so?) and iron(iii) oxide (Fe?).

o?etc. In addition, it cannot dissolve some polymer compounds such as polyethylene (PE) and polypropylene (PP), etc.

Secondary butyl acetate and butyl acetate are isomers of the relationship.

sec-butyl acetate i.e. second butyl acetate molecular formula C6H12O2; Structure: ch3cooch(ch3)ch2ch3

Butyl acetate Molecular Formula: C6H12O2 Structure: CH3Cooch2CH2CH2CH3

The two are isomers, and the indicators are basically the same, but one of the main uses is different, that is, sec-butyl acetate can be used in gasoline to help increase the octane number, while n-butyl ester cannot. In addition, due to the problem of raw materials, sec-butyl ester is about 2,000 yuan less per ton than butyl ester, which is a major reason for customers to use sec-butyl ester.

Here are the data for both products:
