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

解説

組成式SiO2・nH2Oで表されるゲル状の固体.可溶性ケイ酸水溶液を鉱酸で分解し,ゾルを経由してゲル化させ,水洗してつくられる.四面体型SiO2が重合し,重合の切れ目にはOHが結合し,さらにそれが水和した構造をもっている.非晶質含水ケイ酸であって比表面積が大きく(数百 m2 g-1),吸着性がいちじるしいので,乾燥剤として広く用いられる.そのほか,吸着剤,触媒担体などにも用いられる.
森北出版「化学辞典(第2版)

用途

一般脱湿乾燥用、炭酸ガスの吸着除去剤、天然ゴム?合成ゴムの明色補強配合剤、食品添加物 (化学工業日報社)

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

主な用途/役割

エマルション系接着剤、エポキシ樹脂系接着剤、シーリング材に使用される。

化学的特性

Amorphous silica, the noncrystalline form of SiO2, is a transparent to gray, odorless, amorphous powder

化学的特性

white to off-white powder

使用

Silica gel was used on glass plates for preparative TLC and on aluminium sheets for analytical TLC. Silica gel was used in vacuum chromatography and TLC. Silica gel was used in column chromatography.

使用

Silica Gel, 40-63 Micron Particles (cas# 112926-00-8) is a compound useful in organic synthesis.

定義

A gel made by coagulating sodium silicate sol. The gel is dried by heatheating and used as a catalyst support and as a drying agent. The silica gel used in desiccators and in packaging to remove moisture is often colored with a cobalt salt to indicate whether it is still active (blue=dry; pink=moist).

定義

A rigid gel made by coagulatinga sol of sodium silicate andheating to drive off water. It is usedas a support for catalysts and also asa drying agent because it readily absorbsmoisture from the air. The gelitself is colourless but, when used indesiccators, etc., a blue cobalt salt isadded. As moisture is taken up, thesalt turns pink, indicating that thegel needs to be regenerated (by heating).

一般的な説明

Silica gel is a rigid 3D network of colloidal silica. It is exclusively used as a support material for the active titanium(III) centers in Ziegler-Natta catalysts. Silica gel allows a controlled fragmentation lresulting in the formation of uniform polymer particles with narrow particle size distribution and high bulk density. Silica gel is classified as below:
a. Aquagel - pores are filled with water
b. Xerogel - by the process of evaporation, aqueous phase in the pores are removed
c. Aerogel - solvent removed by supercritical extraction

农业用途

A hard granular hygroscopic form of hydrated silica is called silica gel. It is made by heating a coagulated sol of sodium silicate. It is used as a catalyst and a desiccant.

職業ばく露

Amorphous fumed silica is used as a mineral, natural or synthetic fiber. A potential danger to those involved in the production and handling of fumed silica for paint pigments or catalysts. Diatomaceous earth is used in clarifying liquids, in manufacture of fire brick and heat insulators; used as a filtering agent; as a filler in construction materials; pesticides, paints, and varnishes. A potential danger to those involved in mining of diatomaceous earth or fabrication of products there from.

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. [Schenk in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 696 1963.]

不和合性

Silica, amorphous is a noncombustible solid. Generally unreactive chemically. Incompatible with fluorine, oxygen difluoride, chlorine trifluoride. Soluble in molten alkalis and reacts with most metallic oxides at high temperature.

廃棄物の処理

Sanitary landfill.
