Description
a)一般式(II)
の少なくとも1種のケトンを、水溶液中のグリシンおよび水素を用いて、固体の水素化触媒の存在下に、N−アルキルグリシンの形成下に還元的アミノ化する工程、
b)工程a)で得られた混合物から水素化触媒を分離する工程、そして
c)水酸化カリウム、炭酸カリウムまたは炭酸水素カリウムを、工程b)で得られた混合物に添加する工程
を有する本発明による吸収媒体の製造方法である。
のアミノ酸塩を5〜50質量%含んでいる。本発明による吸収媒体は、上述の通り、本発明によるCO2の吸収方法の好ましい実施態様の吸収媒体の場合に記載されている通りの組成を有しているのが好ましい。
例1
N−イソプロピルグリシンカリウムの水溶液の製造
グリシン37.52gを、水500mlおよびアセトン147mlからの混合物中に溶解させた。次に、この溶液のpH値を、85質量%の水酸化カリウム1.49gを添加して8.5の値に調節した。5質量%のパラジウム活性炭(湿分50質量%)10gを添加した後、水素を注入して6barにして、前記混合物を、6barの一定の水素圧で14時間、55℃で撹拌した。引き続き、前記触媒を真空ろ過により分離した。得られた溶液の1H−NMRスペクトルは、グリシンの反応生成物として、N−イソプロピルグリシンおよびN−ジイソプロピルグリシンを50:1のモル比で示した。前記溶液をロータリーエバポレーターで約100mlに濃縮した。その後、85質量%の水酸化カリウム31.6gを添加して、この混合物に水を注いで222gにした。
N−(sec−ブチル)グリシンカリウムの水溶液の製造
グリシン75.1gを水450ml中に溶解させて、この溶液のpH値を、85質量%の水酸化カリウム3.3gを添加して8.5の値に調節した。2−ブタノン108.2gおよび5質量%のパラジウム活性炭(湿分50質量%)7.5gを添加した後、水素を注入して5barにして、前記混合物を5barの一定の水素圧で48時間、55℃で撹拌した。引き続き、前記触媒を真空ろ過により分離した。得られた溶液の1H−NMRスペクトルは、グリシンの反応生成物として、N−sec−ブチルグリシンおよび未反応のグリシンを50:1のモル比で示した。前記溶液をロータリーエバポレーターで約200mlに濃縮した。その後、85質量%の水酸化カリウム60gを添加して、この混合物に水を注いで500gにした。
CO2の吸収容量の測定
CO2負荷およびCO2−Hubの測定のために、第1表に記載された割合のアミノ酸および水酸化カリウムを有する水性の吸収媒体150gを、3℃に冷却された還流冷却器が装着された熱安定性の容器に装入した。40℃もしくは100℃に加熱後、前記容器底のフリット(Fritte)を通して、CO2 14体積%、窒素80体積%、および酸素6体積%からの混合ガスを、流速59l/hで前記吸収媒体を通して、還流冷却器から流出するガス流中のCO2濃度を、CO2分析器を有するIR吸収により測定した。導通されたガス流中および流出したガス流中のCO2含有量の差の積分により、吸収されたCO2量を求め、CO2を有する吸収媒体の平衡負荷を算出した。CO2−Hubは、40℃および100℃で吸収されたCO2量の差として算出した。このようにして測定された40および100℃での平衡負荷(CO2 mol/吸収媒体1kg)およびCo2−Hub(CO2 mol/吸収媒体1kg)は、第1表に記載されている。
