Description
シェルを有する過炭酸ナトリウム粒子の製造
シェルを有する過炭酸ナトリウム粒子の製造のために、EP−B0716640号に記載される方法に従って流動層成長造粒によって水性の過酸化水素溶液と水性のソーダ溶液から製造し、0.78mmの平均粒径x50及び2質量%未満の0.2mm未満の細粒割合を有する過炭酸ナトリウム粒子を使用した。この粒子上にシェル層を、EP−B0863842号の段落[0021]に記載される方法に従って、20質量%のシェル物質の水溶液を流動層中で流動層温度55〜60℃で噴霧し、かつ同時に水を蒸発させることによって塗布した。第1表に質量%で示されるシェル物質量は、結晶水を含まず計算された、使用される過炭酸ナトリウム粒子及びシェル物質の全量に対する、噴霧されたシェル物質の全量を指すものである。
粉末状洗剤中での貯蔵安定性の測定のために、405gのゼオライト含有の15gのTAED及び80gの過炭酸ナトリウムを有する完全粉末状洗剤(Vollwaschmittelpulver)IEC−A* BASE(wfk−Testgewebe GmbH,Krefeld)を、タンブルミキサ中で少なくとも10分間混合した。その混合物を、熱可塑性接着剤で閉じられた撥水的防水加工されたE2洗剤パック(寸法19×14×4.5cm)へと充填した。該洗剤パックを、次いで条件調節キャビネット(Klimaschrank)において35℃及び80%の相対空気湿度で貯蔵した。該洗剤パックを条件調節キャビネットの外で室温にまで冷却した後に、洗剤パックの内容物を、サンプル分配機によって各12gのサンプルに分けた。貯蔵の前後の活性酸素含分を、通常のように過マンガン酸塩滴定によって測定した。貯蔵前の活性酸素含分と、8週間貯蔵後の活性酸素含分とから、粉末状洗剤中での貯蔵安定性についての尺度として、百分率で活性酸素含分の保持率(Oa保持率)を調査した。
シェルを有する過炭酸ナトリウム粒子の製造のための前記試験を、90質量部の硫酸ナトリウム及び10質量部の炭酸ナトリウムのシェル物質組成について、あるいは純粋な硫酸ナトリウムのシェル物質組成について繰り返した。その際、6質量%のシェル物質を噴霧した。比較のために、同じ条件下で、DE2744574号の方法に従って製造された、0.44mmの平均粒径x50及び2質量%未満の0.2mm未満の細粒割合を有する結晶化物の上に、90質量部の硫酸ナトリウム及び10質量部の炭酸ナトリウムからなるシェルを6質量%のシェル物質で塗布した。こうして製造されたシェルを有する過炭酸ナトリウム粒子と共に、80質量部の基礎洗剤IEC−A* BASE(wfk−Testgewebe GmbH,Krefeld)と、15質量部の過炭酸ナトリウムと、5質量部のTAED(Clariant)を混合することによって洗剤調製物を製造した。
