Abstract

The invention provides a tetracyclic decene dimer synthesis method. A tetracyclic decylone is used as an initial raw material and undergoes a carbonyl reduction coupling reaction to synthesize a tension ring cage hydrocarbon tetracyclic decene dimer (C20H28). Compared with the prior art, the synthesis method has the advantages of simple synthetic technology, low cost, high synthetic yield and high product purity, and allows the target compound to be synthesized only through a one-step reaction, the yield to reach about 87% and the purity of the product to reach above 98%; and the tetracyclic decene dimer can be used as the fuel or fuel additive of solid rocket engines.

Description

technical field [0001] The invention relates to a method for synthesizing tensioned ring cage hydrocarbons - tetracyclodedecane dimers (also known as adamantane dimers). The hydrocarbons synthesized by this method have high yield and high purity. High, and the reaction method is simple and low cost. The compound can be used as high-density hydrocarbon fuel or high-energy additive in rocket engines. Background technique [0002] Due to the ring tension energy in the compound molecule, the strained ring cage hydrocarbon increases the calorific value of combustion. When endothermic cracking, once a certain bond is broken, the whole molecule will be broken quickly, releasing energy, and reducing the occurrence of carbon deposition, which has obvious performance advantages. The high-density strained ring cage hydrocarbon is a special type of high-energy-density material (HEDM). All or most of their molecules are composed of carbon and hydrogen, and they have positive heat of fo...
