Chain carbonate
WebJan 1, 2014 · Short-chain dialkyl carbonates, like other short-chain esters, are also suitable solvents for seed oil extraction. Thus, extraction and transesterification can be combined … WebTo make calcium carbonate, shell-building marine animals such as corals and oysters combine a calcium ion (Ca +2) with carbonate (CO 3-2) from surrounding seawater, releasing carbon dioxide and water in the process. Like calcium ions, hydrogen ions tend to bond with carbonate—but they have a greater attraction to carbonate than calcium.

WebPolycarbonate is a polymer chain of bisphenol-A carbonate. Similar to acetal resin, polycarbonate resin is also very strong, fracture resistant, and flexible. However, due to low wear resistance, it should not be used on occlusal surfaces. Polycarbonate is not suitable for full or partial dentures, but it is ideal for provisional crown and bridges.

WebIn organic chemistry a carbonate can also refer to a functional group within a larger molecule that contains a carbon atom bound to three oxygen atoms, one of which is double bonded. These compounds are also known as … In organic chemistry, a carbonate ester (organic carbonate or organocarbonate) is an ester of carbonic acid. This functional group consists of a carbonyl group flanked by two alkoxy groups. The general structure of these carbonates is R−O−C(=O)−O−R' and they are related to esters (R−O−C(=O)−R'), ethers (R−O−R') … See more Carbonate esters have planar OC(OC)2 cores, which confers rigidity. The unique O=C bond is short (1.173 Å in the depicted example), while the C-O bonds are more ether-like (the bond distances of 1.326 Å for the example … See more Organic carbonates are not prepared from inorganic carbonate salts. Two main routes to carbonate esters are practiced: the reaction of an alcohol (or phenol) with phosgene (phosgenation), … See more Organic carbonates are used as solvents in lithium batteries. Due to their high polarity, they dissolve lithium salts. The problem of high viscosity is circumvented by using mixtures for example of dimethyl carbonate, diethyl carbonate, and dimethoxyethane. They are also used … See more Carbonate esters undergo many of the reactions of conventional carboxylic acid esters. With Grignard reagents carbonate esters react to give tertiary alcohols. Some cyclic carbonates are susceptible to polymerization. See more
