糠醛_MSDS_用途_密度_糠醛CAS号【98-01-1】

用途一用作有机合成的原料，也用于合成树脂、清漆、农药、医药、橡胶和涂料等
用途二主要用作工业溶剂，用于制取糠醇、糠酸、四氢呋喃、γ-戊内酯、吡咯、四氢吡咯等
用途三用作分析试剂
用途四用于鞣制面革。宜存放于阴凉、通风的库房，避光保存，防止日光曝晒，远离火源。
用途五 GB 2760—96规定为允许使用的食品用香料；萃取溶剂。主要用于配制各种热加工型香精，如面包、奶油硬糖、咖啡等香精。
用途六糠醛是制备许多药物和工业产品的原料，呋喃经电解还原，还可制成丁二醛，为生产药物阿托品的原料。糠醛的一些衍生物具有很强的杀菌能力，抑菌谱相当宽广。例如糠醛经由5-硝基糠醛，再与盐酸氨基脲缩合得到呋喃西林，是一种消毒防腐药。糠醛是呋喃丙烯酸，糠胺反丁烯二酸，已二酸，糠醇等中间体的原料，广泛用于合成医药，农药，兽药，染料，香料，橡胶助剂，防腐剂等精细化学品。消费糠醛最多的领域是作为溶剂和合成树脂的原料。在用于合成树脂方面，可生产呋喃树脂，糠醛树脂和糠酮树脂等。呋喃树脂亦叫糠醇树脂，糠醛在高压下加氢生成糠醇，将糠醇聚合而得糠醇树脂。这种树脂具有很强的耐碱性，很高的耐热性和耐水性，可用作填缝树脂水泥，防腐衬里，粘结剂。糠醛作为溶剂，可有选择性地从石油，植物油中萃取其中的不饱和组分。用糠醛萃取润滑油和柴油中的芳香组分。提高这些产品质量。在合成橡胶生产中，用糠醛抽提纯化丁二烯和异戊二烯。糠醛能刺激皮肤和粘膜，空气中最高允许浓度为为5ppm。大鼠口服LD50为127mg/kg。
用途七检定钴，测定硫酸盐。测定芳香族胺、丙酮、生物碱、植物油和胆醇的试剂。测定戊糖和多戊糖做标准。合成树脂，精制有机物，硝化纤维溶剂，二氯乙烷萃取剂。

详细合成路线

糠醛上游产品

糠醛下游产品

1.由富含戊聚糖的农产品废料，如玉米芯、棉籽壳、稻糠和甜菜渣等用稀酸水解、脱水并蒸馏而得。

2.糠醛最初从砻糠中得到，农副产品中多含多缩戊糖经水解脱水即生成糠醛。许多农作物的茎，皮，仔壳都含有多缩戊糖，因此都能用作制造糠醛的原料。生产时，将玉米芯，棉子壳或甘蔗渣等原料用硫酸和水蒸气处理，然后经水蒸气蒸馏，分层，减压蒸馏，即可得纯度达99%的产品。糠醛的收离与原料，酸的种类和浓度及其他条件有关，通常与理论收率相差较大。工业上制造糠醛主要有两种方法。加压法适合大规模生产，将原料与稀硫酸在加压下蒸煮，用高压或过热蒸汽带出反应产物，经分馏后得糖醛成品；常压法是将原料与食盐等无机盐及及稀硫酸共煮并同时蒸出糠醛。

3.将100kg玉米芯粉碎成0.5～1cm²的小块，加入25kg 90%的硫酸和125kg食盐与水配成水解液，使水解液的体积为玉米芯的2.5倍。玉米芯与水解液搅匀后，加热至沸，即开始馏出糠醛的稀溶液，冷凝收集于分离器中。静置1～2h分出水相得粗糠醛。用水蒸气蒸馏法精制，得纯品。

精制方法：糠醛放置时产生的酸性物质和树脂，可用水洗后减压蒸馏除去。也可用氯化钙、无水硫酸镁或无水硫酸钠干燥后再进行减压蒸馏。使用过的糠醛的回收方法是用水蒸气蒸馏后再分馏。其他的精制方法有在7%碳酸钠存在下蒸馏，馏出物加2%碳酸钠再蒸馏，最后在800Pa压力下减压分馏可得纯品。
