cellulose acetate fibers are a type of synthetic fiber derived from cellulose. They are one of the earliest synthetic fibers ever developed and were once widely used in various applications. They are made by treating cellulose with acetic acid and acetic anhydride to create cellulose acetate, which is then dissolved in a solvent and spun into fibers through a dry spinning process.
Cellulose acetate is a commercially important thermoplastic, formed from acetylation of cellulose (natural polymer). This reaction converts all primary and secondary hydroxyl groups within the cellulose chain into cellulose triacetate, a fully esterified intermediate, which can be isolated or further processed.
Cellulose nitrate, also known as nitrocellulose, flash paper, guncotton, or celluloid, is a chemical product derived from the natural polymer cellulose. It is a white, odorless, and tasteless substance. Its characteristics are dependent on the degree of substitution.
Carbazole is a heterocyclic aromatic hydrocarbon with the chemical formula C12H9N. It was first isolated from coal tar in 1872 by Graebe and Glaser. Its structure features a dibenzopyrrole, consisting of a five-membered nitrogen-containing ring fused to two benzene rings.
Triethylamine (TEA) is tertiary amine, represented by the chemical formula N(CH2CH3)3. It is a colorless easily flammable liquid with an ammonia-like odor. It one of the most widely used organic amine base in synthetic organic chemistry.
Caprolactam, also known as 2-oxohexamethylenimine or hexahydro-1H-azepin-2-one, is a cyclic amide derived from caproic acid with the formula C6H11NO. It exists as a white, hygroscopic solid with a slight odor. It is used to produce Nylon 6 and the global demand for caprolactam surpasses 5 million tons annually.
Caprolactam, the key ingredient in Nylon-6, can be produced by several routes. The most common method is the convertion of cyclohexanone to cyclohexanone oxime by ammoximation or hydrogen peroxide processes. This oxime then undergoes a Beckmann rearrangement to form caprolactam.
Acetylene also known as ethyne, is a colorless, flammable gas with the chemical formula C2H2. It is the simplest hydrocarbon with a triple bond. It finds widespread use as a fuel in oxy-acetylene welding and cutting due to its incredibly hot flame, and as a chemical building block for various organic chemicals and plastics.
Acetylene is produced by several methods: calcium carbide reaction, partial combustion of hydrocarbons, electric arc processes, thermal cracking with heat carriers and as byproduct of steam cracking.
Acetylene (C2H2) is a simple molecule that finds applications across a wide range of fields. Its unique properties – high flame temperature, rapid heat transfer, and diverse chemical reactivity – make it a valuable material for industries such as metalworking and chemical production.
Calcium carbide, also known as calcium acetylide, is a greyish-black, crystalline compound with the chemical formulat CaC2. Upon contact with water it generates acetylene, a highly flammable gas once widely used for lighting and welding.
γ-Butyrolactone (CAS 96-48-0), also known as γ-hydroxybutyric acid lactone, is a simple organic compound with the formula C4H6O2. It is a hygroscopic and colorless liquid with a faint odor, might seem unremarkable at first glance.
