酒精分类标准及用途.doc

酒精分类、标准及用途Ethanol classification, standard and酒精广泛应用于食品、化学、医药、染料等行业，酒精又是十分重要的淸洁能源通常, 酒精按含杂质多少分为：无水酒精、食用酒精、工业酒精Ethanol widely applies to many industries such as food, chemistry, medicine, dye and etc. In general, ethanol is divided to anhydrous ethanol, edible ethanol and industrial ethanol according to its impurity content.一n 无水酒精 Anhydrous ethanol无水酒精产品质量执行中华人民共和国国家标准GB/T678-2002《化学试剂一无水乙醉标 准》The product quantity of anhydrous ethanol execute the state criteria of the People'sRepublic of China GB/T67&2002 < Chemical Reagent- anhydrous ethanol standard>名称Name优级纯Guara nteereagent分析纯Analyticallypure化学纯Chemicalpure乙醇的质量分数Mass fraction of ethanol (CH3CH2OH ) /%>99.8>99.7>99.5密度Density (20°C) /(g/mL)0.789-0.7910.789-0.7910.789-0.791与水混合试验合格合格合格Test mix with waterQualifiedQualifiedQualified蒸发残渣的质暈分数Mass fraction of evaporation residue /%<0.0005^0.001<0.001酸度(以H+计)Acidity (by H+)/(mmol/100g)<0.02<0.04<0.1碱度(以OH・计)Alkalinity (by OH-)/(mmol/100g)S0.005<0.01<0.03水分的质量分数Mass fraction of water/%S0.2<0.3<0.5甲醇(CH30H)的质量分数Mass fraction of methanol CCH3OH) /%<0.02<0.05<0.2异丙醇[(CH3) 2CHOH]的质量分数Mass fraction of isopropanol[ ( CH3 )2CHOH]/%<0.003<0.01<0.05拨基化合物(以CO计)的质量分数Mass fraction of carbonyl compound (byCO)/%S0.003<0.003S0.005易炭化物质Readily carb on izable substance合格Qualified合格Qualified合格Qualified铁(Fe)的质量分数Mass fraction of ferrum (Fe)/%<0.00001——锌(Ze)的质臺分数Mass fraction of zinc/%<0.00001——还原高猛酸钾物质(以0计)的质量分数/%Mass fractio n of reduci ng potassiumpermanganate substance (by O) /%<0.00025<0.00025<0.0006用途：化学试剂、化学原料.防腐剂、消毒.燃料、冇机溶剂等。

Its impurity indicator is easier than edible ethanol. The ethanol that produced following this standard can not be used for food and drink.工业酒精《GB/T394.1-94》标准Industrial ethanol《GB/T394.1-94》standard项目Item指标Index优等品High-classproduct一等品First-rateproduct合格品Qualifiedproduct粗酒精Crude ethanol夕卜观 Appearance无色透明液体Color less and clear liquid淡黄色液体Faint yellowliquid色度/号 Chroma/No.—气味Smell无异臭no objectional odor—乙醇 Ethanol (20°C, (V/V)) %>96.0>95.5>95.0>95.0硫酸度验号Sulfuric acid degrees Check No. /min<10<80<——氧化时间Oxidization degrees /min130>15—醛(以乙醛计)aldehyde (by < acetaldehyde) /mg L,S530<————杂醉油(以异丁醉+异戊醉计)Fusel ( by Isobutanol + isoamylol)刃0<80<—/mgL.2i甲醇 Methanol/mg L.<800<1200<—酸(以乙酸计)acid (by acetic acid) /mg・Lj<10<20—酯(以乙酸乙酯计)ester (by ethyl acetate) /mg・L仁<30<40——不发挥物Nonvolatile mater/mg-L^<20<25<25—用途：燃料、有机溶剂、乙烯、橡胶、聚乙烯、聚氯乙烯、染料、农药等。
