THF因沸點低，水溶性極好，損耗大，回收率低，回收成本高，三廢處理費用高。長期使用2-MeTHF綜合成本比使用THF低。 2-甲基四氫呋喃沸點較高,容易冷凝回收,揮發(fā)損失少,大氣污染小；在水中溶解度小,通過共沸精餾后回收率高,進入廢水中的2-甲基四氫呋喃含量低,容易處理。 **、四氫呋喃、鹵代烷和苯等環(huán)境不友好的溶劑每年消耗量超過幾十萬噸，其中作為格氏反應溶劑的**和四氫呋喃每年用量在萬噸以上。用2-甲基四氫呋喃替代上述環(huán)境不友好的溶劑符合綠色化工技術(shù)的要求，而且市場前景十分廣闊，經(jīng)濟和社會效益十分明顯。福建2-甲基四氫呋喃廠家哪家好在制藥工業(yè)中可合成抗痔藥磷酸伯氨奎、磷酸氯喹等。</p><div

style="text-indent:25px">工藝使用自制的陽離子交換樹脂作為固體酸催化劑，該款樹脂熱穩(wěn)定性高，高溫使用流失少，使用壽命長。反應完成后，反應液無催化劑殘留，后處理簡單，廢水排放少，環(huán)境友好。該工藝采用了反應精餾的方式，反應過程中產(chǎn)生的水被及時帶出反應體系，促進酯化反應平衡的右移，提高了原料的轉(zhuǎn)化率。該工藝采用了連續(xù)生產(chǎn)的方式，避免了大量的人工操作，產(chǎn)品質(zhì)量穩(wěn)定，有利于規(guī)?；a(chǎn)。以自制的固體酸催化合成TFA的工藝路線有較高的工業(yè)應用價值，如能應用于實踐將會產(chǎn)生良好的經(jīng)濟效益和社會效益。</p><p style="text-indent:25px">四氫呋喃的沸點比較低，將其調(diào)入汽油后使汽油的餾程溫度降低。這一性質(zhì)讓生產(chǎn)超高辛烷值汽油的煉油廠獲得了很大的經(jīng)濟效益。采用四氫呋喃作為反應溶劑，使反應產(chǎn)物和催化劑容易分離，使3-HPA的濃度提高到35%以上。采用水萃取3-HPA，使鈷催化劑的循環(huán)使用率達99.6%，通過控制羰基化反應中的水含量和3-HPA的濃度，使高沸點副產(chǎn)物很少，生成3-HPA選擇性大于90%，使該技術(shù)的工業(yè)化成為可能。產(chǎn)品運輸：運輸車輛應配備相應消防器材及泄漏應急處理設備。嚴禁與氧化劑、食用化學品等混裝混運。禁止使用易產(chǎn)生火花的機械設備和工具裝卸。夏季較好早晚運輸。運輸途中應防暴曬、雨淋，防高溫。中途停留時應遠離火種、熱源、高溫區(qū)。鐵路運輸時要禁止溜放。嚴禁用木船、水泥船散裝運輸。運輸工具上應根據(jù)相關(guān)運輸要求張貼危險標志、公告。甲基，化學式為-CH?，由碳和氫元素組成。</p><div

style="text-indent:25px">2-甲基呋喃由鎳催化在150℃下進行加氫反應即得粗品。經(jīng)脫水、精餾制得成品。另外，在生產(chǎn)乙酰正丙醇時可副產(chǎn)2一甲基四氫呋喃。2-甲基四氫呋喃作為一種環(huán)醚，也是一種路易斯堿，更是一種環(huán)境友好、性能優(yōu)良的獨特的溶劑。近幾年來，由于2-甲基四氫呋喃優(yōu)良的性能和環(huán)境友好的特點，使其在溶劑替代應用領域得以迅速的的發(fā)展：用于替代安全隱患大的四氫呋喃、**等，用作格氏反應溶劑；用于替代高毒性的鹵代烴類、苯類等作為有機合成的反應溶劑或萃取溶劑；應用于有機金屬反應和兩相反應的溶劑。14KPa下，以MeCO(CH2)nCH2Cl為原料與Bu3SnH反應得到環(huán)醚，且產(chǎn)率與環(huán)的大小有關(guān)。當n＝2時，所得2-甲基四氫呋喃的產(chǎn)率為98％。將RCH2CH2OCHR’CH2R(R＝Br，Cl；R’＝H，Me)在極性溶劑中用鋅粉、鉀汞齊或鋰汞齊的作用下發(fā)生分子內(nèi)偶聯(lián)反應得2-甲基四氫呋喃。利用水溶液Cu(II)堿金屬氯化物催化氧化1，3-戊二烯得到2-甲基四氫呋喃。四氫呋喃可以通過氫氧化鈉置于密封瓶中在暗處保存。福建2-甲基四氫呋喃廠家哪家好</p><p style="text-indent:25px">聚四氫呋喃主要用作嵌段聚氨酯或嵌段聚醚聚酯的軟鏈段。福建2-甲基四氫呋喃廠家哪家好</p><p style="text-indent:25px">順酐催化加氫法：順酐和氫氣從底部進入內(nèi)裝鎳催化劑的反應器，產(chǎn)物中四氫呋喃與γ-丁內(nèi)酯比例可通過調(diào)整操作參數(shù)加以控制。反應產(chǎn)物與原料氫氣冷卻至50℃左右進入洗滌塔底部，使未反應的氫氣及氣態(tài)與液態(tài)產(chǎn)物分離，未反應的氫氣及氣態(tài)產(chǎn)物經(jīng)洗滌后循環(huán)到反應器，液態(tài)產(chǎn)物經(jīng)蒸餾而得四氫呋喃產(chǎn)品。該工藝可在0～(5∶1)范圍內(nèi)任意調(diào)整γ-丁內(nèi)酯與四氫呋喃的比例，順酐的單程轉(zhuǎn)化率達99.9%，四氫呋喃選擇性為85%～95%，產(chǎn)品含量達99.97%。該工藝具有催化劑性能好、流程簡單、投資少等特點。4-丁二醇脫水環(huán)化法：其工藝過程為：向反應器中加入1087kg 22%的硫酸水溶液，在100℃以110kg/h的速度加入1，4-丁二醇，塔頂溫度維持在80℃，以大約110kg/h的速度從塔頂?shù)玫胶?0%四氫呋喃的水溶液。加入50t 1，4-丁二醇后，從反應器中排除約70kg焦質(zhì)。將焦質(zhì)進行過濾，得到的硫酸水溶液可以重新使用，這一過程的四氫呋喃收率可以達到99%以上。硫酸是四氫呋喃工業(yè)生產(chǎn)中使用較早的催化劑，也是現(xiàn)今生產(chǎn)中應用較多的催化劑。此工藝技術(shù)成熟，工藝比較簡單，反應溫度較低，四氫呋喃收率較高，但硫酸易腐蝕設備，污染環(huán)境。福建2-甲基四氫呋喃廠家哪家好</p></p><br
