化学的特性
Clear colorless oil
使用
Paraffin Oils is a useful organic solvent for isolating the nucleus of the gian amphibian oocyte.
調製方法
Mineral oil is obtained by distillation of petroleum. The lighter
hydrocarbons are first removed by distillation and the residue is
then redistilled between 330–390°C. The distillate is chilled and the
solid fractions are removed by filtration. The filtrate is then further
purified and decolorized by high-pressure hydrogenation or sulfuric
acid treatment; the purified filtrate is then filtered through
adsorbents. The liquid portion obtained is distilled and the portion
boiling below 360°C is discarded. A suitable stabilizer may be
added to the mineral oil;
一般的な説明
Transparent colorless oily liquid. Practically tasteless and odorless, even when warmed.
空気と水の反応
Flammable. Insoluble in water.
反応プロフィール
OIL. [MINERAL] may be incompatible with strong oxidizing agents like nitric acid. Charring may occur followed by ignition of unreacted oil and other nearby combustibles. In other settings, mostly unreactive. Not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents. Burns exothermically when heated sufficiently or when ignited in the presence of air, oxygen or strong oxidizing agents.
危険性
Inhalation of vapor or particulates can causeaspiration pneumonia. Combustible liquid. Upperrespiratory tract irritant. Questionable carcinogen.
健康ハザード
Highly refined mineral oil mist
is of low toxicity.
火災危険
PARAFFIN is combustible.
応用例（製薬）
Mineral oil is used primarily as an excipient in topical pharmaceutical
formulations, where its emollient properties are exploited as an
ingredient in ointment bases. It is additionally used in
oil-in-water emulsions,as a solvent, and as a lubricant in
capsule and tablet formulations, and to a limited extent as a mold-release agent for cocoa butter suppositories. It has also been used in
the preparation of microspheres and as a vaccine adjunct.
Therapeutically, mineral oil has been used as a laxative.It is indigestible and thus has limited absorption.
Mineral oil is used in ophthalmic formulations for its lubricant
properties. It is also used in cosmetics and some food products.
安全性プロファイル
A human teratogen by
inhalation that causes testicular tumors in
the fetus. Inhalation of vapor or particulates
can cause aspiration pneumonia. A skin and
eye irritant. Highly purified food grades are
of low toxicity. Questionable human
carcinogen producing gastrointestinal
tumors. Slightly combustible liquid when
exposed to heat or flame. To fight fire, use
dry chemical, CO2, foam. When heated to
decomposition it emits acrid smoke and
fumes.
貯蔵
Mineral oil undergoes oxidation when exposed to heat and light.
Oxidation begins with the formation of peroxides, exhibiting an
‘induction period’. Under ordinary conditions, the induction period
may take months or years. However, once a trace of peroxide is
formed, further oxidation is autocatalytic and proceeds very
rapidly. Oxidation results in the formation of aldehydes and
organic acids, which impart taste and odor. Stabilizers may be added to retard oxidation; butylated hydroxyanisole, butylated
hydroxytoluene, and alpha tocopherol are the most commonly used
antioxidants.
Mineral oil may be sterilized by dry heat.
Mineral oil should be stored in an airtight container, protected
from light, in a cool, dry place.
純化方法
Treat the oil with fuming H2SO4 (care), then wash it with water and dilute aqueous NaOH, then percolate it through activated silica gel. Paraffin Wax. Melt the wax in the presence of NaOH, wash it with water until all of the base had been removed. The paraffin is allowed to solidify after each wash. Finally, 5g of paraffin is melted by heating it on a water-bath, then shaken for 20-30minutes with 100mL of boiling water and and dry the melt under vacuum.
不和合性
Incompatible with strong oxidizing agents.
