左右，達(dá)到385～393s。
乙炔氨推進(jìn)劑充分利用了乙炔高能量和液氨高溶解性能等特點(diǎn)，與火箭煤油和液氫相比具備很多，包括：

乙炔能夠大幅降低液氨的毒性；乙炔溶解于液氨后爆炸危險(xiǎn)性明顯下降；乙炔在氨中的溶解度較大，

可以方便地調(diào)變比例獲得適宜的推進(jìn)劑組成；乙炔的加入能夠有效提高液氨的點(diǎn)火和燃燒性能，提高

乙炔和氨的分離，目前沒(méi)有現(xiàn)成的色譜柱，滕州市浩瀚色譜儀器技術(shù)服務(wù)有限公司，，研發(fā)出《乙炔氨液體推進(jìn)劑測(cè)定專用填充柱》，乙炔和氨得到有效分離。

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.
