Editing Chemistry

This will be where stuff about chemistry goes. Feel free to edit as you like; I'm starting with lists of reagents and glassware that I will be bringing, and will add photos later today.

==Glassware==

All items are 24/40 standard taper unless otherwise specified. Some items are not glassware, but are used in reaction setups.

Prices are from Sigma-Aldrich's catalogue. In reality these can be had much more cheaply on ebay.

* Liebig condenser, 200mm ($55.10)
* Allihn condenser, 200mm ($172.40)
* 3-neck 500mL round-bottom flask ($94.20)
* 500mL round-bottom flask ($30.70)
* 250mL round-bottom flask ($27.00)
* 100mL round-bottom flask ($23.50)
* 50mL round-bottom flask ($22.90)
* 2x50mL round-bottom flask with distiller arm (not standard taper)
* Addition funnel, 125mL ($113.40)
* Separating funnel, 100mL (not standard taper; use a 1-hole stopper for an adapter) (~$20 from American Science and Surplus)
* Stillhead adapter ($68.10)
* Vacuum adapter ($47.10)
* Claisen adapter ($56.70)
* 0-360 degree thermometer
* 500mL beaker
* 250mL beaker
* 2x200mL beakers
* 40mL beaker
* 500mL one-arm Erlenmeyer flask (not standard taper)
* Buchner funnel
* 100mL graduated cylinder
* 10mL graduated cylinder
* 10mL burette
* Evaporating dish
* Aquarium pump with hoses (attaches to condenser for cooling it down) (~$25 at any aquarium store)
* Test tubes, various sizes, lots of them
* 2 ring stands with clamps
* Hose clamps
* Mortar and pestle

==Reagents==

* 1 gallon methanol
* 1 gallon phosphoric acid
* 1 gallon hydrochloric acid, 12M
* ~1lb potassium hydroxide
* Calcium chloride, anhydrous (drying agent)
* Magnesium sulfate, anhydrous (drying agent)

==Things that are broken but could be fixed==

* A 500mL round-bottom longneck distillation flask with the distiller arm broken off. If someone has an acetylene torch, this could be repaired by fusing a glass tube onto it, or the hole could be sealed up and the flask used for a reflux reaction flask.
* A Liebig condenser, not standard taper, with part of the stillhead end in several pieces. Again, fixable with a hot enough torch.
* A vacuum aspirator with a bunch of pipe-fitting adapters. It works, but currently the adapters are on there really tight and I can't get them off. If someone has a plumber's wrench and a bench vise, this is easy to fix.

==Workshops we could do==

* Distillation and drying. 99% ethanol is really expensive, but we can make it cheaply with everclear (or cheap vodka) and a little bit of work.
* Liquid-liquid extraction and organic separation -- polar vs. non-polar solvents, how to use them
* Column chromatography
* Steam extraction from organic materials -- make your own essential oils and hydrosols
* Acid/base extraction
* Build a rotary evaporator
* How to set up a reaction under reflux conditions
* Fractional distillation
* Build a fume hood

==Things we should have on hand==

There are many reagents which we should have in stock and which can be acquired easily from hardware stores or photography supply stores. Here are some, please add more:

* Acetone (hardware store)
* Xylene (hardware store)
* Toluene (hardware store, though do they sell it in California?)
* 99% isopropyl alcohol (pharmacy)
* Glacial acetic acid (photography supply)
* Dichloromethane (hardware store)
* Denatured alcohol (hardware store)
* Naphtha (hardware store)
* 99% ethanol (can be purchased at places like The Science Shop in San Jose, but is very expensive; cheaper to make our own)
* Silica gel (finer ground than the stuff that comes in packets, but we can grind it up in a mortar)
* Calcium chloride (hardware store, "Damp-Rid")
* Magnesium sulfate, anhydrous (pharmacy; buy Epsom salts and bake them in an oven to dehydrate, then put in a bag and crush into little chunks)
* Astroglide, glycerin/paraben-free (for greasing glass joints)
* Nitric acid, 70% (electronics supply -- used for etching PCBs)
