Product uses

One of the main uses of CAS No.27247-96-7 is as a precursor to triazine herbicides.

It is converted into products such as simazine, atrazine, and promethazine, and is

widely used in agriculture to control weeds in crops such as corn, sugarcane, and

cotton. These herbicides are effective against weeds before and after emergence,

making them a popular choice for farmers.

Product Specification

Product package

190 kg/barrel or according to customer requirements of CAS No.27247-96-7.

Ether Compounds In the earliest times, people added butyl ether, amyl ether, diethylene

glycol monobutyl ether, etc. to diesel at a dosage of 50% - 100% (volume fraction), so

that the ethers themselves served as fuel, but they were relatively expensive. Later,

ether - type cetane number improvers with relatively good improvement effects such as

alkyl or cycloalkyl ethers, cyclic ethers, and ethers containing dialkoxyalkanes were
discovered one after another.

This kind of improver has good miscibility with traditional diesel, generally up to 90%,

but the addition amount is relatively large. Recently, a new type of ether (RO(CHO)ₘR, m

= 2 - 6, R is a CₙHₙ₊₁ alkyl chain, n = 1 - 10) has been reported in the literature. Its

addition amount is generally more than 1% (mass fraction) and it can be synthesized by

the reaction of formaldehyde and alcohol or dialkoxymethane under the action of a catalyst,

that is

2ROH + mCH2O → RO(CHO)mR + H₂O

RO(CH2O)mR + (m - 1)CH₂O → RO(CH2O)mR

Dinitro Compounds The cetane number improvement effect of mononitro compounds is

very small, and they may even reduce the cetane number. However, dinitro compounds

have a very good improvement effect. Structurally, the two nitro groups must be on the

same carbon atom. Such compounds include alkyl, cycloalkyl and aryl dinitro compounds.

Among them, cycloalkyl dinitro compounds have the best improvement effect, while aryl
dinitro compounds CAS No.27247-96-7 have the worst effect.

The addition effect of alkyl dinitro compounds is also very good. In particular, for

2,2 - dinitropropane, when the addition dosage is 0.15% (mass fraction), the cetane

number will increase by 9 - 19 units. Compared with alkyl dinitro compounds, cycloalkyl

dinitro compounds have better stability and better miscibility with diesel, making them

relatively good improvers. However, this type of improver has a relatively high nitrogen

content, and more NOₓ will be generated during combustion,causing environmental

pollution.

Fatty Acid Derivatives In recent years, while using vegetable oil products as alternatives

to diesel, natural vegetable oils have started to be used as raw materials for synthesizing

cetane number improvers, and efforts have been made to develop some fatty acid

derivatives as effective cetane number improvers. The most reported ones at present are
the corresponding nitrates synthesized from fatty acids.

Nitrates obtained from vegetable oils through different processing methods have different

advantages and disadvantages,and their addition effects also vary. For example, the fatty

acid ethylene glycol nitrates CAS No.27247-96-7 of C₁ - C₈ [RCOO(CH₂CHO)ₙNO₂]

have a relatively good addition effect. Moreover,compared with nitrate compounds, they

have a lower nitrogen content, which is beneficial for reducing NOₓ pollution.

However, if this improver is to be produced on a large scale,many difficulties in the

production process must be overcome. Therefore, it has not been commercialized yet.

Besides nitrate derivatives, other derivatives such as primary amines,tertiary amines,

amides, alcohols, and acetates also have the effect of improving the cetane number.

Research has proven that primary amines, tertiary amines, and amides are relatively

effective cetane number improvers among them, but there are not many related reports

at present.

Other Types of Compounds Recently, it has been reported in the literature that the mixture

obtained by dissolving carotene in toluene under the protection of an inert gas and then

adding alkyl nitrate (accounting for 1/4 of the volume of the solution) CAS No.27247-96-7

also has a very good cetane - number - improvement effect.

In addition, a mixture of levulinate and formate obtained by separation of substances

synthesized from plant materials and olefins can be used as an effective cetane - number

- improvement group. Besides the several types introduced above, azo compounds,

azide compounds, oxalates, nitrites, dithiocarbamates, sulfonamide nitro - olefins, sulfones,

sulfoxides, aldehydes, ketones, amines, hydrazines,etc. can also be used as cetane

- number - improvers.
