Intercage hydrogen-bonds and hydrophobic interactions between-butyl groups direct the hierarchical assembly of the cages into a permanent porous material. The chiral phosphoric acid-containing frameworks can be high efficient and recyclable heterogeneous Brnsted acid catalysts for asymmetric [3+2] coupling...
How inclusion of additives affect silicone rubbers? Silicone rubbers generally contain additives to obtain high performance for a desired application. Crosslinking - Silicone rubbers are cured/crosslinking either by: Peroxide crosslinkers (benzoyl peroxide, 2,4-dichlorobenzoyl peroxide, t-butyl perbenzoat...
(c = 100 g/l) Method D: 5 g surfactant + 45 g ethylene glycol monobutyl ether solution (c = 250 g/l) Method E: 5 g surfactant + 25 g ethylene glycol monobutyl ether solution (c = 250 g/l) *** The pH of the Pluronic® RPE types can fall slightly in storage, but this ...
The molecular weight and molecular weight distribution, crystallinity, form and proportion of comonomer (if used), and isotacticity all influence the properties of polypropylene. The methyl groups in isotactic polypropylene, for example, are oriented on one side of the carbon backbone. This structure...
What functional groups are present in progesterone?What is the line structure for butylpentoate?Elaborate on the different types of reversible enzyme inhibitors.Name the given diene and state whether the ball-and-stick model shows the diene in the s-cis or s-trans conformation....
Isotactic (iPP)– Methyl groups (CH3) arranged on one side of the carbon chain Syndiotactic (sPP)– Alternating methyl group (CH3) arrangement Basic Chain Structures of PP Depending on how it is produced and formulated, PP can be: hard or soft, ...
In the oxidation step of this reaction, 4-tert-butylcyclohexanone is formed from when a C-H bond is lost while a C-O bond is gained to create a carbonyl. In the reduction step, 4-tert-butylcyclohexanol is formed when the carbonyl is converted into an alcohol when a nucleophilic hydride...
Microplastics are one of the most concerning groups of contaminants that pollute most of the surroundings of the Earth. The abundance of plastic materials
Unnecessary derivatization (use of blocking groups, protection/ deprotection, temporary modification of physical/chemical processes) should be minimized or avoided if possible, because such steps require additional reagents and can generate waste.
