Metal catalysis in aliphatic isocyanate-alcohol reactions was written by Oberth, Adolf E.;Bruenner, Rolf S.. And the article was included in Industrial & Engineering Chemistry Fundamentals in 1969.Reference of 20324-33-8 This article mentions the following:
A number of metal catalysts for the aliphatic isocyanate-alc. reaction were studied. Partial alcoholysis of the metal compound is required for the activation of the alc. Compounds which suppress alcoholysis also reduce the catalytic activity. The equilibrium involving the alcoholytic products can account for the effects of concentration of catalyst, alc., and alcoholytic products on the rate of the catalyzed reaction. In the experiment, the researchers used many compounds, for example, 1-((1-((1-Methoxypropan-2-yl)oxy)propan-2-yl)oxy)propan-2-ol (cas: 20324-33-8Reference of 20324-33-8).
1-((1-((1-Methoxypropan-2-yl)oxy)propan-2-yl)oxy)propan-2-ol (cas: 20324-33-8) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. But on the other hand, ethers undergo cleavage by reaction with acids. Ethyl ether is an excellent solvent for extractions and for a wide variety of chemical reactions. It is also used as a volatile starting fluid for diesel engines and gasoline engines in cold weather. Dimethyl ether is used as a spray propellant and refrigerant. Methyl t-butyl ether (MTBE) is a gasoline additive that boosts the octane number and reduces the amount of nitrogen-oxide pollutants in the exhaust. The ethers of ethylene glycol are used as solvents and plasticizers.Reference of 20324-33-8
