炭酸Mg 化学特性,用途語,生産方法

定義

本品は、塩基性炭酸マグネシウム脱水物又は正炭酸マグネシウム含水物である。

解説

化学式 MgCO3 。天然にはマグネサイト (菱苦土鉱) として産出する。マグネシウム塩溶液に炭酸ナトリウムを加えて得られる炭酸塩は,塩基性塩 (MgCO3)4・Mg(OH)2・5H2O で,これを工業上あるいは薬用上で炭酸マグネシウムと呼ぶ。無水塩 MgCO3 は菱面体の結晶で,比重 3.04。水に難溶,酸および二酸化炭素水溶液に可溶。熱あるいは酸により容易に分解し,二酸化炭素を放出するので,二酸化炭素発生源に用いられる。3水塩 MgCO3・3H2O は無色斜方晶系結晶,100℃で脱水する。断熱材,研磨材,おしろい,歯磨き粉に用いられるほか,ミネラルウォーター,顔料,紙などの製造に使用される。

説明

Magnesium carbonate has the molecular formula of MgCO3 and the molecular weight of 84.3145 g/mol.For the most part,Mg2+ forms several hydrated and basic carbonates that are stable and occur in nature.
The calcite structure of magnesium carbonate has the form wherein Mg2+ is surrounded by six O2- atoms. The dihydrate composition has a triclinic structure, while the trihydrate has a monoclinic structure. References to “light” and “heavy” magnesium carbonates actually refer to the magnesium hydroxycarbonates. A space-filling structure of the anhydrous salt is seen in the above diagram where the triangular CO3 2- groups are clearly visible.

化学的特性

Light, bulky, white powder. Soluble in acids; very slightly soluble in water; insoluble in alcohol. Noncombustible.

化学的特性

At room temperature, linolenic acid is a colorless liquid; soluble in most organic solvents; insoluble in water. Combustible.

使用

Magnesium Carbonate is an anticaking agent and general purpose food additive. it is practically insoluble in water but is more soluble in water containing carbon dioxide. it imparts a slightly alkaline reaction to the water. it is used as an alkali in sour cream, butter, and canned peas. it is used as an anticaking agent in table salt and dry mixes. it assists in providing clarity in algin gels and functions as a filler in dental impression materials.

使用

Magnesium carbonate (MgCO3) is found in a mixture of natural minerals. It can also be produced in several ways, including pumping carbon dioxide through magnesium oxide or magnesium hydroxide. It is used in pharmaceuticals such as magnesium citrate and as a desiccant to keep hydroscopic products from caking (table salt) and to strengthen rubber and produce dyes, inks, and cosmetics.

使用

Magnesium salts, heat insulation and refractory, rubber reinforcing agent, inks, glass, pharmaceuticals, dentifrice and cosmetics, free-running table salts, antacid, making magnesium citrate, filtering medium. In foods as drying agent, color retention agent, anticaking agent, carrier.

定義

The term magnesium carbonate is generally reserved for the synthetic, pure variety. The naturally occurring material is called magnesite.
