What is Heneicosane?

The source of n-eicosane is primarily a by-product in the manufacturing of ethylene from oil cracking, as well as it is primarily made use of as a reduced value-added solvent. For that reason, studying the catalytic discerning oxidation of the C-H bond of n-heconocane can generate oxygen-containing industrial items with greater included worth as well as even more useful application value. After further processing as well as use, these oxygen-containing substances can be of wonderful usage in lots of industries such as medicine, organic chemicals, dyes, etc. Consequently, study on the selective oxidation of hydrocarbons represented by n-21-inosane has great clinical research study value and useful significance.

Heneicosane Uses

Heneicosane is among the main resources commonly utilized in industrial manufacturing of drugs, spices and plastics, and is likewise an important precursor raw material for numerous chemical products. It can likewise be utilized to manufacture a range of fine chemicals and usual natural reactions, such as Cannizzaro reaction, benzoin condensation response as well as Perkin response. The most crucial thing is that it additionally has really close-to-life usages as well as can be made use of as an additive in food, cosmetics as well as medicines. delay.

Heneicosane Application

Application 1.
CN201410178932.5 reports a black beetle attractant, which is identified because it mostly includes β-trans-ocimene 20%-70%, α-farnesene 10%-50%, and linalool 1%- 10%, p-ethyl acetophenone 1%-10%, oranthrin 1%-10%, cis-3-hexene-acetate 1%-10%, cis-3-hexen-1-ol 1 %-10%, n-tetradecane 1%-10%, n-pentadecane 1%-10% and also Heneicosane 1%-10% are combined as well as prepared. The above percentages are mass percentages. The black carabine attractant as well as lure core of today invention have high level of sensitivity, do not contaminate the environment as well as are low in cost, so they have excellent promo as well as application value and show excellent trapping activity in the field.

Application 2.
CN201480006363.4 reports a structure for bring in expectant mosquitoes to lay eggs in a preferred setting. The make-up for leading mosquitoes to lay eggs consists of several attractants and also an N-P-K additive, in which the N-P-K additive is a mixture having the chemical elements nitrogen, phosphorus and potassium. The attractants can be customized to offer compositions for advertising oviposition by different varieties of mosquitoes. The above structure might be adjusted to give a structure for advertising oviposition by mosquitoes of the genus Anopheles. The composition might likewise consist of cooked whey, Heneicosane, and/or methyl myristate to give a make-up for advertising oviposition by Aedes mosquitoes. The structures may also be adjusted to provide structures for promoting oviposition by Culex mosquitoes.

Heneicosane Preparation

A preparation technique for single prep work of Heneicosane, the actions are:
( 1 ). Mix 1510.5 g (10mol) of n-pentane bromide and also 3053.5 g (10mol) of n-hexadecane bromide uniformly to create a combination of alkane bromide and alloted;

( 2 ). Consider 483g (21mol) of metal sodium and also cut it right into small strips with a location of about 1 × 3cm2, and also alloted;

( 3 ). Put 50g of alkyl bromide blend as well as 20g of sodium metal right into the reaction kettle, mix as well as raise the temperature to 80 ° C, depend on response heating, and also maintain the response temperature at 120 ° C, constantly include the remaining alkyl bromide mixture dropwise, as well as include steel Salt, maintain it in a small reflux state. After the enhancement is finished, manage the temperature at 140 ° C and also maintain it continuous for 2 hours;

( 4 ). Add 400 grams of 95% ethanol and also 1000 ml of water in turn, separate the organic matter, wash with water until neutral, completely dry with anhydrous magnesium sulfate, gather the 260-280 ° C fraction by purification, include 600g of concentrated potassium sulfate to the fraction as well as laundry till neutral. The acid layer is light yellow. Wash the natural phase with water to nonpartisanship and also completely dry it. Gather 500g of 96% n-decane and also 600g of 98% Heneicosane with a fractionation column. The content of n-alkanes gotten is 96% to 98%.

The molar ratio of n-pentane as well as n-hexadecane bromide is 1:1. The response kettle is a three-necked flask composed of a stirrer, a separatory funnel and also a reflux condenser. The solid oxidant is concentrated sulfuric acid or Acidic potassium permanganate.
