크롬산 나트륨 C화학적 특성, 용도, 생산
화학적 성질
Sodium chromate, including the hexahydrate, is yellow crystalline solids that can also be used in solution. Disodium dichromate (10588-01-9):용도
Sodium chromate anhydrous is used as a corrosion inhibitor in the petroleum industry, wood preservative and dyeing auxiliary in the textile industry. It is also used to prepare pigments for paints and inks. It also finds use in pharmaceuticals to determine red blood cell volume. In synthetic chemistry, it is utilized as an oxidant to convert primary alcohols and secondary alcohols to carboxylic acids and ketones respectively.정의
ChEBI: An inorganic sodium salt consisting of sodium and chromate ions in a 2:1 ratio.일반 설명
Sodium chromate is a yellow crystalline solid dissolved in a liquid medium, probably water. Sodium chromate is soluble in water. Sodium chromate is toxic by inhalation, ingestion and/or skin contact. Sodium chromate is noncombustible. Sodium chromate is used to make pigments for paints and inks, other chemicals, and as a wood preservative.공기와 물의 반응
Water soluble.반응 프로필
SODIUM CHROMATE is a strong oxidizer. Sodium chromate absorbs moisture from the atmosphere. Incompatible with strong acids . In contact with combustible materials may cause fire. Toxic chromium oxide fumes may form in fire [USCG, 1999].위험도
Toxic material.건강위험
Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.화재위험
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways.잠재적 노출
Used to make dyes, inks, pigments, and other chromates; in leather tanning, a corrosion inhibitor in circulating water systems; metal treatment; a drilling mud additive; chemical intermediate for chromium catalysts; colorimetry, oxidizing agent; bleaching agent; an algicide, fungicide, insecticide; in wood preservation.운송 방법
