|Section2= |Section3= |Section6= }} Trimethylolethane trinitrate (TMETN), also known as metriol trinitrate (METN, MTN, METRTN) or nitropentaglycerin, is a nitro ester. It is a high explosive similar to nitroglycerin. It is a transparent oily liquid, colorless to light brown. It is odorless. It is used in some solid propellants and smokeless powders as a plasticizer. Its chemical formula is CH3-C(CH2-O-NO2)3. TMETN was first prepared and patented in Italy under name Metriolo. Germans began producing it before WWII when it was demonstrated to be an erosion and flash reducing agent in smokeless powders. It is a liquid explosive with properties similar to nitroglycerin but more stable to heat. It is prepared by nitration of trimethylolethane (metriol). It does not induce headaches. TMETN can be initiated by friction, impact, and electrostatic discharge. It can be used as a high viscosity plasticizer-binder together with nitrocellulose, but its poor coloiding properties made such use rare; long-term milling can however assist here; success can also be achieved by adding an inert plasticizer and a volatile solvent/colloiding agent.〔(Explosive composition comprising HMX, RDX, or PETN and a high viscosity nitrocellulose binder plasticized with TMETN - The United States of America as represented by the Secre... )〕 TMETN is miscible with ether and acetone. It is insoluble in 95% sulfuric acid.〔(Trimethylolethane Trinitrate )〕 TMETN can be used as a plasticizer together, or as an alternative to, triethyleneglycol dinitrate (TEGDN). TMETN can also be used as a monopropellant.〔(Liquid Nitrate Ester Monopropellant Composition - Camp, Albert T )〕 Triethylene glycol dinitrate, diethylene glycol dinitrate, and trimethyloleate trinitrate are being considered as replacements for nitroglycerin in propellants.〔(Guns and Ordnance: Ammunition and Explosives - Storming Media )〕 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Trimethylolethane trinitrate」の詳細全文を読む スポンサード リンク
