#chemical intermediate

• Alkali cellulose — An intermediate product obtained in the chemical industry by treating cellulose with a concentrated solution of sodium hydroxide (caustic soda). This compound plays an essential structural role in the manufacture of viscose, rayon, and cellophane, facilitating the subsequent chemical reactivity of fibers by altering the macromolecular molecular arrangement.
• Aldol — A bifunctional organic compound containing both an aldehyde group (-CHO) and a hydroxyl group (-OH) attached to a carbon atom in the beta position (b-hydroxyaldehyde). The term specifically designates 3-hydroxybutanal, obtained via the aldol condensation of two acetaldehyde molecules, serving as a critical intermediate in the industrial synthesis of butadiene and other macromorphological compounds.
• Aminophenol — A bifunctional organic compound with amphoteric character, derived from phenol by replacing a hydrogen atom on the aromatic ring with an amino group (-NH2). It has three positional isomers (ortho, meta, and para), of which para-aminophenol is the most industrially important, serving as a key structural intermediate in the synthesis of paracetamol, hair dyes, and photographic developers.
• Aminone — A generic name rarely used to describe a cyclic organic molecular structure or an unsaturated ketone structurally modified by grafting an amino group. This isolated technical term is encountered in laboratory jargon for classifying certain synthesis intermediates used in preparing dyes or pharmaceutical compounds.
• Antravon — A commercial or technical name attributed to an organic compound derived from anthracene, historically used as an industrial intermediate in the manufacture of highly stable synthetic dyes or certain chemical impregnating agents for textile materials. This term refers to a complex aromatic structure optimized to withstand thermal degradation and the action of oxidants in industrial technological processes.
