Use of molecular sieves in synthesis. Aldehyde and ketone di-sec-alkyl acetals was written by Roelofsen, D. P.;Van Bekkum, H.. And the article was included in Synthesis in 1972.Product Details of 1132-95-2 This article mentions the following:
Mol. sieves adsorbed H2O in reaction of secondary alcs. with aldehydes and ketones to give 62-94% (>98% purity) RR1η(OR2)2 (I). Thus, 40 g powd. type 5a com. mol. sieve was added to 0.10 mole RR1ηO, 0.40 mole R2OH, 150 ml cyclohexane, and 3.8 g p-MeC6H4SO3H.H2O, and the mixture stirred 2 hr at 0° to give I (R,R1..sigma.2 given): Me, Me, Me2CH; Me, Me, cyclohexyl; Me2CH, H, Me2CH; Me2CH, H, MeEtCH; Me2CH, H, cyclohexyl; Ph, H, Me2CH and I[RR1(CH2)5], R2 = Me2CH and MeEtCH. In the experiment, the researchers used many compounds, for example, 1,1-Diisopropoxycyclohexane (cas: 1132-95-2Product Details of 1132-95-2).
1,1-Diisopropoxycyclohexane (cas: 1132-95-2) belongs to ethers. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive. Autoxidation is the spontaneous oxidation of a compound in air. In the presence of oxygen, ethers slowly autoxidize to form hydroperoxides and dialkyl peroxides. If concentrated or heated, these peroxides may explode. To prevent such explosions, ethers should be obtained in small quantities, kept in tightly sealed containers, and used promptly.Product Details of 1132-95-2
