Bottles of di-tert-butyl dicarbonate buildup of internal pressure in sealed containers caused by its slow decomposition to di-tert-butyl carbonate and ultimately tert-butanol and CO 2 in the presence of moisture. For this reason, it is usually sold and stored in plastic bottles rather than glass ones.
Properties Chemical formula. C 6 H 10 O 5: Molar mass: 162.141 g·mol −1 Appearance Clear, colorless liquid Density: 1.101 g/mL at 25 °C ... Di-tert-butyl dicarbonate
di-tert-butyl dicarbonate (H 3 C−) 3 C−C 2 O 5 −C(−CH 3) 3, also known as Boc anhydride. It is one of the oxocarbon anions, consisting solely of oxygen and carbon. The anion has the formula − O−C(=O)−O−C(=O)−O − or C 2 O 2− 5. Dicarbonate salts are apparently unstable at ambient conditions, but can be made under pressure ...
tert-Butyl alcohol is used as a solvent, ethanol denaturant, paint remover ingredient, and gasoline octane booster and oxygenate.It is a chemical intermediate used to produce methyl tert-butyl ether (MTBE) and ethyl tert-butyl ether (ETBE) by reaction with methanol and ethanol, respectively, and tert-butyl hydroperoxide (TBHP) by reaction with hydrogen peroxide.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
tert-Butyloxycarbonyl protecting group. The tert-butyloxycarbonyl protecting group or tert-butoxycarbonyl protecting group [1] (BOC group) is an acid-labile protecting group used in organic synthesis. The BOC group can be added to amines under aqueous conditions using di-tert-butyl dicarbonate in the presence of a base such as sodium hydroxide:
An important example is di-tert-butyl tricarbonate (H 3 C−) 3 C−C 3 O 7 −C(−CH 3) 3, an intermediate in the synthesis of di-tert-butyl dicarbonate. [1] The term tricarbonate is sometimes used for salts that contain three carbonate dianions in their covalent structure or stoichiometric formula, such as cerium tricarbonate Ce 2 (CO 3) 3.
Di-tert-butyl tricarbonate extrudes carbon dioxide in the presence of various catalysts to form di-tert-butyl dicarbonate. [2] Long-chain carbon dioxide oligomers are likewise expected to decompose exothermically. [3]
