储存条件

储存注意事项储存于阴凉、通风的库房。库温不宜超过37℃。远离火种、热源。避光保存、包装要求密封,不可与空气接触。应与氧化剂、碱类、食用化学品分开存放,切忌混储。不宜大量储存或久存。采用防爆型照明、通风设施。禁止使用易产生火花的机械设备和工具。储区应备有泄漏应急处理设备和合适的收容材料。

稳定性

1.对金属无腐蚀性,可用铁、软钢、铜或铝制容器贮存。在空气中或遇光逐渐变为棕色,故应避光、充入惰性气体密封贮存。糠醛在氧气、空气、二氧化碳、氮气中放置40天后,生成氧化物(树脂状)的量分别为1.7%,0.3%,0.1%,0.05%。在糠醛中加入对羟基二苯胺、二苯胺、碘化镉、对苯二酚、连苯三酚或β-萘酚等,添加量0.1%即可有效地防止氧化。在糠醛中添加0.001%~0.1%的N-苯基取代脲、硫脲或萘胺,能够防止在60~170℃加热时生成树脂。

2.化学性质:糠醛具有醛的性质。例如与亚硫酸氢钠能生成加成化合物,氧化变成呋喃甲酸,还原得到糠醇。在浓氢氧化钾溶液中发生Cannizzaro反应,生成糠醇和呋喃甲酸。与氰化钾反应生成联糠醛(furoin)。与氨反应生成糠酰胺,与胺反应生成Schiff碱。将糠醛与钠石灰一起加热至350~400℃,或者用镍或氧化锌与铬,五氧化二钒作催化剂加热至200℃,转变成呋喃。精制的糠醛放置时,由于受到空气中氧的作用,发生分解、聚合等一系列复杂的反应,使颜色变深。加热或光照都能加速其分解、聚合反应。

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。
