Embodiment 1

[0027] 1. PECH synthesis: install a mechanical stirrer, an automatic temperature controller, a nitrogen conduit and a three-necked flask in a cold water bath, add 145g of nonanol, start stirring, slowly introduce dry nitrogen, and then inject 1gBF3·OEt2, and wait until the temperature drops to When the temperature is below 30°C, 222g ECH is added dropwise for 40 minutes, the temperature is controlled at 30-35°C, and the reaction is stirred for 4 hours. After the reaction is completed, add 120# solvent oil to control the density below 0.88, wash with water 2-3 times to separate impurities, and distill under reduced pressure to remove 120# solvent oil to obtain 332g of colorless liquid PECH. After GPC analysis, the number average molecular weight Mn=366

[0028] 2. Synthesis of azide: Add 332g PECH into a three-necked flask equipped with a mechanical stirrer, then add 30g of self-made azidation catalyst to fully stir and dissolve, then add 118g of NaN3, heat up to 80°C and stir f...

Embodiment 2

[0037] 1. PECH synthesis: install a mechanical stirrer, an automatic temperature controller, a nitrogen conduit and a three-necked flask in a cold water bath, add 200g of isotridecyl alcohol, start stirring, slowly introduce dry nitrogen, and then inject 1.7g of anhydrous SnCl4, When the temperature dropped below 30°C, 222g of ECH was added dropwise for 40 minutes, the temperature was controlled at 30-35°C, and the reaction was stirred for 5 hours. After the reaction is completed, add 120# solvent oil to control the density below 0.88, wash with water 2-3 times to separate impurities, and distill under reduced pressure to remove 120# solvent oil to obtain 384g of colorless liquid PECH. After GPC analysis, the number average molecular weight Mn=422 .

[0038] 2. Synthesis of azide: Add 384g PECH into a three-necked flask equipped with a mechanical stirrer, then add 35g of self-made azidation catalyst to fully stir and dissolve, then add 119g of NaN3, heat up to 90°C and stir fo...

Abstract

The invention relates to a trinitride capable of upgrading the quality and effect of fuel. The trinitride is a main product which is obtained from the raw materials of saturated alkyl alcohol or phenol, epichlorohydrin and sodium azide, a few of by-products and a mixture containing an azide catalyst, wherein (1) the main product is glycidyl azide polymer, namely GAP for short; (2) the by-products are a chloride-containing isomer of the glycidyl azide polymer, namely GAP-CL for short; (3) the azide catalyst is a home-made azide catalyst for reaction synthesis in the second step; and (4) an intermediate is polyepichlorohydrin, namely PECH for short, is an intermediate product synthesized by the trinitride, and is not a component of the trinitride, wherein any moL number of a chlorine group is replaced with the sodium azide of which the polymerization number n is 1-8, n is not an integer, and saturated alkyl R is alcohol or phenol with the atom number is 2-18. According to the trinitride, the big problems of security and environmental protection in synthesis are solved, and the production cost and the use cost are greatly reduced.

Description

technical field [0001] The invention relates to an azide for upgrading the quality and efficacy of fuel oil and a safe and environmentally friendly synthesis method, belonging to the technical field of fuel oil. Background technique [0002] Fuel energy conservation and emission reduction is a major issue related to the national economy and the people's livelihood, and new breakthroughs are urgently needed. At present, the synthesis process of polyazide glycidyl ether has high cost, serious safety and environmental protection problems, a large amount of fuel additive, insufficient safety and stability for storage in fuel oil, and insufficient development of functional applications. Contents of the invention [0003] The purpose of the present invention is to provide an azide that upgrades the fuel quality and efficacy and a safe and environmentally friendly synthesis method so as to better improve the fuel use effect. [0004] In order to achieve the above object, the tec...
