style="text-indent:25px">酒精的用途是很多的，不同濃度的酒精用途是不一樣的，你們了解多少呢?其實(shí)我們可以了解的事很多的，我們的酒精在生活中的用途是很***的，不知道你們了解多少呢?小編在這里想給各位來介紹一下不同濃度酒精的用途，我知道具體的你們是不是那么清楚的，那么下面一起來看看吧!<br/> 一、95%的酒精用做燃料<br/> 醫(yī)療單位常需使用酒精燈、酒精爐，點(diǎn)燃后用于配制化驗(yàn)試劑或藥品制劑的加熱，也可用其火焰臨時(shí)消毒小型醫(yī)療器械。<br/> 二、70%-75%的酒精用于滅菌消毒<br/> 用于包括皮膚消毒、醫(yī)療器械消毒、碘酒的脫碘等。<br/> 有人以為，酒精濃度越高，消毒效果越好，這是錯(cuò)誤的。酒精消毒的作用是凝固細(xì)菌體內(nèi)的蛋白質(zhì)，從而殺死細(xì)菌。但95%的酒精能將細(xì)菌表面包膜的蛋白質(zhì)迅速凝固，并形成一層保護(hù)膜，阻止酒精進(jìn)入細(xì)菌體內(nèi)，因而不能將細(xì)菌徹底殺死。如果酒精濃度低于70%，雖可進(jìn)入細(xì)菌體內(nèi)，但不能將其體內(nèi)的蛋白質(zhì)凝固，同樣也不能將細(xì)菌徹底殺死。只有70%-75%的酒精即能順利地進(jìn)入到細(xì)菌體內(nèi)，又能有效地將細(xì)菌體內(nèi)的蛋白質(zhì)凝固，因而可徹底殺死細(xì)菌。<br/>

乙醇是優(yōu)異的油品增氧劑和改良劑之一，可有效提高汽油辛烷值，降低汽車有害尾氣及固體顆粒物的排放。當(dāng)前，世界燃料乙醇的使用量已超過9000萬噸，美國、巴西等國家多年來一直使用乙醇作為汽油的添加劑。眾所周知，我國要在2020年全國范圍內(nèi)推廣使用車用乙醇汽油，基本實(shí)現(xiàn)全覆蓋。據(jù)此估算，到2020年，我國燃料乙醇的需求量將達(dá)1200萬噸，而目前我國的燃料乙醇產(chǎn)量*為約250萬噸，市場缺口預(yù)計(jì)達(dá)950萬噸。我國人多地少，大規(guī)模使用糧食來生產(chǎn)燃料乙醇的思路既不現(xiàn)實(shí)也不經(jīng)濟(jì)。在此種形勢下，研究煤制乙醇技術(shù)替代傳統(tǒng)的糧食發(fā)酵法，對(duì)減少我國糧食工業(yè)消耗、提高能源安全以及助力環(huán)境保護(hù)具有重要的戰(zhàn)略意義。當(dāng)前，國內(nèi)外正在研發(fā)的煤制乙醇技術(shù)路線主要有以下三條：煤經(jīng)合成氣一步法制乙醇；煤經(jīng)甲醇羰基化制乙酸，乙酸加氫轉(zhuǎn)制乙醇；煤經(jīng)二甲醚羰基化制乙酸甲酯，乙酸甲酯加氫制乙醇。本文對(duì)此進(jìn)行了一下梳理。1煤經(jīng)合成氣直接制乙醇煤經(jīng)合成氣直接制乙醇過程可極大簡化現(xiàn)有的生產(chǎn)工藝，具有重要的研究價(jià)值。從學(xué)術(shù)意義上來講，該過程可加深和豐富人們對(duì)合成氣反應(yīng)體系內(nèi)在規(guī)律的認(rèn)識(shí)，推動(dòng)碳一化學(xué)催化理論的發(fā)展，有著潛在的應(yīng)用價(jià)值。需催化劑、助催化劑，使2分子乙醛生成1分子乙酸乙酯。</p><div
