1) Baker formol-calcium
贝克氏甲醛钙溶液
2) formaldehyde solution
甲醛溶液
1.
Methylene diphenyl dicarbamate(MDC),an intermediate for the production of methylene diphenyl diisocyanate,was directly synthesized from dimethyl carbonate(DMC),aniline,and formaldehyde solution over the bifunctional H4SiW12O40-ZrO2/SiO2 catalyst.
研究了以H4SiW12O40-ZrO2/SiO2为催化剂,碳酸二甲酯(DMC)、苯胺和甲醛溶液为原料,一步催化合成二苯甲烷二氨基甲酸甲酯(MDC)的反应,考察了反应时间、反应温度和H4SiW12O40负载量等反应条件对催化性能的影响。
2.
The DNA extraction,in General,from samples stored in formaldehyde solution is inefficient,especially extracted from small individual.
提取了保存于5%甲醛溶液中的单只中华哲水蚤基因组DNA。
4) formaldehyde aqueous solution
甲醛水溶液
1.
Compared with traditional technique which takes o-chloroaniline and formaldehyde as materials,paraformaldehyde is used instead of formaldehyde aqueous solution for this method.
与以邻氯苯胺和甲醛水溶液为原料的传统工艺相比,用多聚甲醛代替甲醛水溶液,使多聚甲醛在酸催化下慢慢分解生成甲醛,可以保证与邻氯苯胺的反应在比较缓和的条件下进行,避免了大量树脂状物质的生成,提高了产品收率。
