石油醚運(yùn)用過程中要注意什么呢?石油醚是無色透明液體，有火油氣味。首要為戊烷和己烷的混合物。不溶于水，溶于無水乙醇、苯、氯仿、油類等大都有機(jī)溶劑。易燃易爆，與氧化劑可激烈反應(yīng)。首要用作溶劑和油脂處理。通常用鉑重整抽余油或直餾汽油經(jīng)分餾、加氫或其他方法制得。實(shí)驗(yàn)室過柱子時，常用石油醚(PE)和乙酸乙酯(EA)做展開劑。一般有30～60℃、60～90℃、90～120℃等沸程規(guī)格。毒理學(xué)材料：LD50：40mg/kg(小鼠靜脈)LC50：3400ppm4小時(大鼠吸入)。緩慢毒性：大鼠吸入，230天，夜間活動減少，網(wǎng)狀內(nèi)皮系統(tǒng)輕度異常反應(yīng)，末梢神經(jīng)有髓鞘退行性變，軸突輕度變化腓腸肌肌纖維輕度萎縮。其在人體內(nèi)也有積蓄性，為神經(jīng)性毒劑。健康損害：其蒸氣或霧對眼睛、粘膜和呼吸道有刺激性。中毒表現(xiàn)可有炙烤感、咳嗽、喘息、喉炎、氣短、***、惡心和吐逆。該品可引起周圍神經(jīng)炎。對皮膚有激烈刺激性。環(huán)境損害：對環(huán)境有損害，對水體、土壤和大氣可形成污染。燃爆危險：該品極度易燃，具強(qiáng)刺激性。皮膚觸摸：當(dāng)即脫去污染的穿著，用肥皂水和清水徹底沖刷皮膚。眼睛觸摸：當(dāng)即提起眼瞼，用很多活動清水或生理鹽水徹底沖刷至少15分鐘。福建**高沸點(diǎn)芳烴廠家供應(yīng)芳烴分為輕芳烴和重芳烴，苯環(huán)連接烷烴或烯烴的碳鏈長的是重芳烴，苯環(huán)連接烷烴或烯烴的碳鏈短的是輕芳烴。</p><div

溶劑油餾程（30-240），D系列餾程（90-370），白油餾程（250-450）。詳細(xì)參看《溶劑油白油分類簡介》。溶劑**業(yè)的發(fā)展十分迅速，其應(yīng)用領(lǐng)域也不斷擴(kuò)大，在食用油浸出、膠黏劑、油漆、化工聚合、橡膠、清洗、氣霧劑、醫(yī)藥中間體、金屬清洗、油墨等方面都有用途。相對來說我國國內(nèi)溶劑油品種比較少，目前，仍以6號、120號和200號以及D系列溶劑油為主流品種。目前我國生產(chǎn)溶劑油的原料大致有五種：1.催化重整抽余油2.油田穩(wěn)定輕烴3.直餾汽油4.石腦油前四類屬于石油類，目前市場上還有第五類5.煤化穩(wěn)定輕烴抽余油：餾程是65～150℃，能生產(chǎn)6號及120號溶劑油，因原料經(jīng)過了加氫精制處理，所以生產(chǎn)出的溶劑油能達(dá)到國家標(biāo)準(zhǔn)。油田穩(wěn)定輕烴：因含丁烷、戊烷較多，所以產(chǎn)出丁烷、戊烷溶劑所占比例較大，生產(chǎn)出的6號及120號溶劑油的硫含量和芳烴含量達(dá)不到國家標(biāo)準(zhǔn)，需要進(jìn)行脫硫、脫芳烴。直餾汽油：主要生產(chǎn)200號溶劑油，也需進(jìn)行精制才能得到合格產(chǎn)品。石腦油：餾程30-220℃，能生產(chǎn)戊烷、異己烷、6號、120號及200號溶劑油，必須進(jìn)行脫芳脫硫脫色處理才能達(dá)到國標(biāo)。

溶劑油中的芳烴與磺化劑反應(yīng)生成低沸點(diǎn)磺酸，分離酸相與油相把磺酸切除，從而達(dá)到脫芳烴的目的。該反應(yīng)為放熱反應(yīng)，溫度不宜過高或過低，一般控制在30～50℃。反應(yīng)后溶劑中由于溶有少量的SO3而呈酸性，需用堿中和，然后水洗至中性。因?yàn)榇斯に囈褜偬蕴夹g(shù)，目前，國內(nèi)很少有煉廠再采用此技術(shù)。國內(nèi)正己烷生產(chǎn)廠家大多采用加氫精餾工藝，而國外正己烷生產(chǎn)多采用分子篩吸附工藝。例如美國Richfielcd公司和Watson公司，以重整抽余油為原料，通過循環(huán)使用兩個或兩個以上床層吸附。芳烴，是芳香烴的簡稱，芳烴是指含苯環(huán)的烴，通常指分子中含有苯環(huán)結(jié)構(gòu)的碳?xì)浠衔?，是閉鏈類的一種。</p><div

溶劑油脫芳工藝之加氫法：1959年由美國謝夫隆公司研發(fā)，國內(nèi)由大慶石油學(xué)院研發(fā)，1966年在大慶建成***個裝置。加氫按工藝主要分為，一段加氫裂化，二段加氫裂化及串聯(lián)加氫裂化，目前大多數(shù)煉廠均采用串聯(lián)加氫工藝。催化加氫脫芳烴技術(shù)，可使6號溶劑油中的芳烴含量降到；加氫法優(yōu)點(diǎn)是，產(chǎn)品清潔度高，苯轉(zhuǎn)化為環(huán)己烷，硫轉(zhuǎn)化為硫化氫。缺點(diǎn)是，投資大，物耗大。目前，國內(nèi)大多數(shù)廠家均采用加氫工藝。其他煉廠如洛陽石化，鎮(zhèn)海石化，長嶺煉化，中科院山西煤碳化學(xué)研究所等加氫工藝都是大同小異。未來加工煤基的煉廠會在生產(chǎn)正己烷過程中降低戊烷、丁烷含量。必須說明兩者產(chǎn)出的97%以上正己烷幾乎沒有差別。而且煤化產(chǎn)出的正己烷含量更高，雜峰少。重芳烴主要來源于重整重芳烴、裂解汽油重芳烴和煤焦油。福建**高沸點(diǎn)芳烴廠家供應(yīng)</p><p
