性质描述: 无色单斜楔形结晶;白色颗粒或结晶性粉末。相对密度1.587(25/4℃)。在160-186℃分解。易溶于水,1g该品可溶于0.5ml水;170ml乙醇;约100ml甲醇。在空气中稳定。

生产方法: 蔗糖大量来自甘蔗糖和甜菜,甘蔗含蔗糖约15-20%,甜菜含10-17%。其他各种果实;种子;叶;花;根中也有不同的含量。将甘蔗榨出法液或将甜菜切片用水提出糖汁,用石灰澄清法或兼用亚硫酸饱充法,除去糖汁中的杂质,过滤后将滤液真空蒸浓,再结晶分离而得粗糖,再经脱色;重结晶而得精糖。

用途: 蔗糖是最普通的食和糖,也用于制柠檬酸;焦糖;转化糖;透明肥皂等。蔗糖在高浓度时能抑制细菌生长,医药上可作防腐剂;抗氧剂的药片赋形剂等。1980年世界原糖产量为8710万t,其中蔗糖5200万t,甜菜糖3500万t。来自甘蔗和甜菜的蔗糖受自然条件的限制发展缓慢,世界缺糖情况较较严重。另外,各种特殊需要,促旱灾了新甜料的研究和发展,现在已经找出了许多天然甜料和合成甜料。试剂蔗糖用于1-萘酚的测定,也用于钙;镁分离及生物培养基的制备。
