| 外観 | 白色の微粒 | | 定義 | 本品は、含水ケイ酸であり、次の化学式で表される。
xは製法により異なり、０を含む | | 溶解性 | 水、エタノール及びアセトンにほとんど溶けない。水酸化ナトリウム溶液に加熱すると溶ける。 | | 用途 | 分取クロマトグラフ用。有機合成(フェノール性MOM基の高選択的脱保護)(Wako Organic Square No.13,p16(Sep.2004)。 | | 用途 | クロマトグラフ用吸着剤、ガス検知管材料。 | | 用途 | PCB定量シリカゲルカラムクロマトグラフ用。 | | 用途 | 中圧分取クロマトグラフ用吸着剤。 | | 化粧品の成分用途 | 不透明化剤、抗ケーキング剤、口腔ケア剤、皮膚コンディショニング剤、親水性増粘剤、吸着剤、研磨.スクラブ剤、増量剤 | | 化学的特性 | White powder | | 使用 | Silica gel, wide pore is mainly used for the dehydrated purification of the industrial gases, the clearance of the organic acids and high polymers in the insulative oil, the purification and separation of the medicines. It is also used in column chromatography without applied pressure (gravity pulled). | | 使用 | Excipient. | | 定義 | LICHROSORB(R) RP8 is an adsorbent consisting of amorphous silica produced by the reaction of sodium silicate with mineral acid. | | 純化方法 | Before use as a drying agent, silica gel is heated in an oven, then cooled in a desiccator. Conditions in the literature range from heating at 110o for 15hours to 250o for 2-3hours. Silica gel has been purified by washing with hot acid (in one case successively with aqua regia, conc HNO3, then conc HCl; in another case it was digested overnight with hot conc H2SO4), followed by exhaustive washing with distilled water (one week in a Soxhlet apparatus has also been used), and prolonged oven drying. Alternatively, silica gel has been extracted with acetone until all soluble material was removed, then dried in a current of air, washed with distilled water and oven dried. Silica gel has also been washed successively with water, M HCl, water, and acetone, then activated at 110o for 15hours. Silicon monoxide [10097 -28 -6] M 44.1, m > 1700o, d 4 2.18. Purify the monoxide by sublimation in a porcelain tube in a furnace at 1250o (4hours) in a high vacuum (10-4mm) in a stream of N2. It is obtained as brownish black scales.
