文档介绍：氢氧化钙羰基化合成甲酸钙的动力学研究及初步设计
摘要
甲酸钙的用途广泛,不仅是国内外新开发的一种饲料添加剂,适用于各类动物饲料中作酸化剂、防霉剂、抗菌剂、,还可以用作高硫燃料的脱硫剂、食品工业添加剂、石油工业钻探助剂、植物生长调节剂、水泥强悍剂、制革工业助剂,自从1998年农业部确定了甲酸钙作为饲料添加剂的合法地位后,对甲酸钙的合成研究引起了人们的广泛关注。
国内外市场研究表明,在仔猪日粮中添加1%~%甲酸钙可以明显改善断奶仔猪生产性能。德国的研究发现,%甲酸钙可以改善饲料转化率7%~8%,%可减少仔猪腹泻的发生。郑建华(1994)%甲酸钙,饲养25d,%,%,%%,仔猪下痢显著减少。吴天星(2002)在三元杂交断奶仔猪日粮中添加1%甲酸钙,日增重提高了3%,饲料转化率提高了9%,%。其他需要注意的是:甲酸钙的使用在断奶前后有效,这是因为仔猪自身分泌的盐酸随着年龄而加强;甲酸钙含有30%容易吸收的钙质,在配制饲
料时要注意调整好钙磷的比例。
 作为新型饲料添加剂。喂甲酸钙增重,用甲酸钙作仔猪饲料添加剂,能促进仔猪食欲和降低腹泻率。甲酸钙以中性形式添加于饲料中,仔猪采食后经消化道的生化作用,会游离出微量甲酸,从而达到降低胃肠道PH值的目的。起到促进消化道中有益菌群的生长,减少仔猪下疾的作用。在仔猪断奶后头几周,%的甲酸钙,可使仔猪生长速度提高12%以上,饲料转化率提高4%。

ABSTRACT
A calcium widely used, not only is home to a newly developed feed additives, suitable for all types of animal feed acidifiers, preservatives, antibacterial agents, can also be used as ahigh-sulfur fuel desulfurization agent, food industry additives, oil industry drilling additives, plant growth regulators, cement powerful agent, leather industry chemicals, since 1998 the Ministry of Agriculture identified as a feed additive calcium formate legal status, on the synthesis of calcium formate aroused attention.
Domestic and international market research showed that piglets add 1% to % Calcium can significantly improve the performance of weaned piglets. German study found that in weaned piglets add % calcium formate can improve feed conversion rate of 7% to 8%, adding percent to reduce the
incidence of diarrhea. Zheng Jianhua (1994) in 28-day-old weaned piglets diets supplemented with % calcium formate, feeding 25d, ADG increased by %, feed conversion rate of %, protein and energy utilization increased by % and %, a significant reduction in diarrhea in piglets. Wu Stars (2002) in crossbred piglets diets supplemented with 1% calcium formate, increased by 3% daily gain, f
