Keto-Enol tautomerism

α-substitution of carbonyl compounds takes place at the carbon adjacent to the C=O, through an enol or enolate intermediate, due to
α-H being acidic

An acetal is a molecule with two single bonded oxygens attached to the same carbon atom.

alkoxy

Sat, 23 Aug 2008 19:30:00 GMT

the alkoxyl group is an alkyl (carbon and hydrogen chain) group linked to oxygen thus: R-O. The range of alkoxy groups is as great, the simplest being methoxy (-OCH3). An ethoxy group (-OCH2CH3) is found in the organic compound phenetol, C6H5OCH2CH3 which is also known as ethoxy benzene. Related to alkoxy groups are aryloxy groups.

Description	select and extract tiddlers from your TiddlyWiki documents and save them to a separate file

ExportTiddlersPlugin lets you select and extract tiddlers from your TiddlyWiki documents using interactive control panel lets you specify a destination, and then select which tiddlers to export. Tiddler data can be output as complete, stand-alone TiddlyWiki documents, or just the selected tiddlers ("PureStore" format — smaller files!) that can be imported directly into another TiddlyWiki, or as an RSS-compatible XML file that can be published for RSS syndication.

Documentation

Revisions

2008.05.27 [2.7.0] added ability to 'merge' with existing export file. Also, revised 'matchTags' functionality to be more robust and more efficient
please see ExportTiddlersPluginInfo for additional revision details

Classification of catalysts

Fri, 18 Jul 2008 10:48:00 GMT

see block 5 table 2, p.30

Metals
- hydrogenation
  - examples Fe, Ni, Pt, Pd, Cu,
- oxidation
  - examples Ag, Pt

Metal oxides
- dehydration
  - examples alumina, magnesia, silica
- oxidation
  - examples vanadium (V) oxide, nickel oxide, zinc oxide, chromium oxide, complex metal molybdates, mulitmetallic oxide compositions

Acids
- isomerisation, alkylation, cracking
  - examples silica-aluminas, zeolites in acid form

solid catalysts

Fri, 18 Jul 2008 10:48:00 GMT

heterogenous catalysis takes place at solid surface (usually gas/solid interface)
Higher solid surface area = increased reaction rates
very small crystals may sinter at high temps; to avoid this they are dispersed on/in support or carrier; or included in non-sintering inorganic material, a stabilizer/strucural promoter/textural promoter
chemical/electronic promoters increase catalyst activity by changing chemical composition of catalyst

A good solid catalsyt will

have good activity
be selective, promoting formation of desired product
be suffieciently stable, with minimal
- poisoning - impurity reducing catalytic activity (but note selective poisoning eg Lindlar catalyst
- fouling - physical blockage

GettingStarted

To get started with this blank TiddlyWiki, you'll need to modify the following tiddlers:

SiteTitle & SiteSubtitle: The title and subtitle of the site, as shown above (after saving, they will also appear in the browser title bar)
MainMenu: The menu (usually on the left)
DefaultTiddlers: Contains the names of the tiddlers that you want to appear when the TiddlyWiki is opened

You'll also need to enter your username for signing your edits:
