The Role Of Aluminum Phosphide In Agriculture

wallpapers Industry 2021-01-22
Aluminum is a silver-white light metal. There is malleability. Commodities are often made into rods, sheets, foils, powders, ribbons and filaments. It can form an oxide film to prevent metal corrosion in humid air. Aluminum powder and aluminum foil can burn violently when heated in the air and emit a dazzling white flame.
 
Anhydrous aluminum chloride is a commonly used catalyst in the petroleum industry and organic synthesis; for example, the alkylation reaction of aromatic hydrocarbons, also known as Friedel-Crafts alkylation reaction, is catalyzed by anhydrous aluminum trichloride, Aromatics and halogenated hydrocarbons (or olefins and alcohols) undergo electrophilic substitution reactions to generate alkyl substituted aromatics. Aluminum chloride hexahydrate can be used to prepare deodorants, safety disinfectants, and petroleum refining.
 
Aluminum bromide is a commonly used catalyst for organic synthesis and isomerization.
 
When aluminum phosphide is exposed to humidity or acid, it emits highly toxic phosphine gas, which can poison pests. It is used as a fumigant for barn insecticide in agriculture.
Aluminum sulfate is often used as filler, mordant, water purifier and fire extinguishing agent in papermaking, oil clarifier, oil deodorizing and decolorizing agent, and used in the manufacture of sedimentary color, fireproof cloth and medicine.
 
Cryolite is sodium hexafluoroaluminate, which is often used as an insecticide in agriculture; it is used as an opacifier in the manufacture of glass and enamel in the silicate industry.
 
Alum, which is obtained by heating and extracting alumite, is an important water purifying agent, dye mordant, and used as astringent in medicine. Aluminum nitrate can be used to tan leather and make incandescent electric filaments, and can also be used as a mordant; aluminum silicate is often used to make glass, ceramics, paint pigments and paint, rubber and plastic fillers, etc., silica-aluminum gel is hygroscopic, It is often used as a catalyst carrier for petroleum catalytic cracking or other organic synthesis.
