乙炔，俗称电石气，是炔烃化合物系列中体积小的化合物，由于其具有较高的燃烧热值，在金属焊

接方面有重要应用。液氨是一种重要的化工原料，具有较强的溶解性能和蒸发潜热，广泛用于化学肥

料、硝酸、冶金等工业。乙炔氨推进剂是将乙炔溶解于液氨中，通过调整乙炔含量，得到综合性能优

异的高能液体推进剂。根据文献报道，乙炔氨推进剂的比冲比现有火箭煤油高约15～20s，比甲烷高5s

左右，达到385～393s。
乙炔氨推进剂充分利用了乙炔高能量和液氨高溶解性能等特点，与火箭煤油和液氢相比具备很多，包括：

乙炔能够大幅降低液氨的毒性；乙炔溶解于液氨后爆炸危险性明显下降；乙炔在氨中的溶解度较大，

可以方便地调变比例获得适宜的推进剂组成；乙炔的加入能够有效提高液氨的点火和燃烧性能，提高

能量比冲；液氨的加入能够降低乙炔的燃烧温度；乙炔氨成本低廉，价格比火箭煤油稍高，但远低于

液氢，较高；与液氢需要特殊的存储运输条件相比，乙炔氨推进剂存贮压力低于液氢，温度高

于液氢，易于存储运输。

乙炔和氨的分离，目前没有现成的色谱柱，滕州市浩瀚色谱仪器技术服务有限公司，，研发出《乙炔氨液体推进剂测定专用填充柱》，乙炔和氨得到有效分离。

Special packed column for determination of acetylene ammonia liquid propellant
Special packed column for the determination of acetylene ammonia liquid propellant Details:

Stationary phase: dedicated
Model: HH-NH3-C2H2

Acetylene, commonly known as calcium carbide gas, is the smallest compound in the series of acetylene compounds. Due to its high combustion heat value, it is used in metal welding.
There are important applications in the connection. Liquid ammonia is an important chemical raw material with strong solubility and latent heat of evaporation. It is widely used in chemical fertilizers.
Materials, nitric acid, metallurgy and other industries. The acetylene ammonia propellant dissolves acetylene in liquid ammonia, and the overall performance is excellent by adjusting the acetylene content.
Different high energy liquid propellants. According to the literature, the specific impulse of acetylene ammonia propellant is about 15-20s higher than the existing rocket kerosene and 5s higher than methane.
Left and right, reaching 385 ~ 393s.
The acetylene ammonia propellant makes full use of the high energy of acetylene and the high solubility of liquid ammonia. It has many advantages compared with rocket kerosene and liquid hydrogen, including:
Acetylene can greatly reduce the toxicity of liquid ammonia; the risk of explosion after acetylene is dissolved in liquid ammonia is significantly reduced; the solubility of acetylene in ammonia is large.
It is convenient to adjust the ratio to obtain a suitable propellant composition; the addition of acetylene can effectively improve the ignition and combustion performance of liquid ammonia and improve
Energy ratio; the addition of liquid ammonia can reduce the combustion temperature of acetylene; acetylene ammonia is cheaper and the price is slightly higher than rocket kerosene, but much lower than
Liquid hydrogen, cost-effective; compared with liquid storage requires special storage and transportation conditions, acetylene ammonia propellant storage pressure is lower than liquid hydrogen, high temperature
In liquid hydrogen, easy to store and transport.

The separation of acetylene and ammonia, there is no ready-made column, Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd., with the times, developed a "filled column for the determination of acetylene liquid propellant", acetylene and ammonia are effectively separated, this The technology is exclusively developed by Haohao Chromatography and is currently applying for patent protection.
