Ethylene oxide is an organic compound with the formula C 2 H 4 O. It is a cyclic ether and the simplest epoxide: a three-membered ring consisting of one oxygen atom and two carbon atoms. Ethylene oxide is a colorless and flammable gas with a faintly sweet odor.
In organic chemistry, an epoxide is a cyclic ether, where the ether forms a three-atom ring: two atoms of carbon and one atom of oxygen. This triangular structure has substantial ring strain, making epoxides highly reactive, more so than other ethers. They are produced on a large scale for many applications.
A polymerization in which a cyclic monomer yields a monomeric unit which is acyclic or contains fewer cycles than the monomer. Note: If monomer is polycyclic, the opening of a single ring is sufficient to classify the reaction as ring-opening polymerization. Modified from the earlier definition. [1] [2]
C 3 H 4 O is a chemical formula that represents each of several actual and hypothetical compounds that differ in structure, but each consist of three atoms of carbon, four of hydrogen, and one of oxygen. The following compounds are among them:
The epoxidation can take place either in a homogeneous reaction by peracids [2] or heterogeneous catalysis (e.g. silver and molecular oxygen). [ 3 ] [ 4 ] [ 5 ] In industrial production the heterogeneously catalyzed synthesis is preferred because of better atom economy , a simpler separation of the product and easier recycling of catalyst.
Tetrahydrofuran (THF), or oxolane, is an organic compound with the formula (CH 2) 4 O. The compound is classified as heterocyclic compound, specifically a cyclic ether. It is a colorless, water-miscible organic liquid with low viscosity. It is mainly used as a precursor to polymers. [8]
C12-C14 alcohol glycidyl ether (AGE) is an organic chemical in the glycidyl ether family. [2] It is a mixture of mainly 12 and 14 carbon chain alcohols, also called fatty alcohols that have been glycidated. It is an industrial chemical used as a surfactant but primarily for epoxy resin viscosity reduction. [3]
Dimethyldichlorosilane (Si(CH 3) 2 Cl 2) is a key precursor to cyclic (D 3, D 4, etc.) and linear siloxanes. [5]The main route to siloxane functional group is by hydrolysis of silicon chlorides:
