工业上脂肪酸或酯的加氢需要250～300℃的温度和3000～4000磅/吋~2的压力。实现这样苛刻的条件需要较高的成本,所以就要研究低压和低温的工艺过程。对于脂肪酸加氢,金属钯并不特别有效。Fischer等人报道了Ru/C(碳为载体的钌催化剂)对于全氟羧酸是有效的。类似地,在1500磅/吋~2压力下用RuO_2催化剂,乙醇酸的还原是很容易的。然而同样的催化剂还原醋酸却需要7000磅/吋~2的压力。Grimm指出Rh_2O_3在150℃和2000磅
Commercial hydrogenation of fatty acids or esters requires a temperature of 250 to 300 ° C and a pressure of 3,000 to 4,000 psi. To achieve such harsh conditions require a higher cost, it is necessary to study the process of low pressure and low temperature. Palladium is not particularly effective for the hydrogenation of fatty acids. Fischer et al. Reported that Ru / C (carbon supported ruthenium catalyst) is effective for perfluorocarboxylic acids. Similarly, the reduction of glycolic acid is very easy with a RuO 2 catalyst at 1500 psig. However, the same catalyst requires about 7,000 psi to reduce acetic acid. Grimm pointed out that Rh 2 O 3 is at 150 ° C and 2000 pounds
