'''Calculations for 10% phenol film and 10% phenol stock solution''' | |||
*1.373E22 OH groups in 1 gram of pooh × 0.1= 1.373E21 | |||
*1.373E21 ÷ 6.022E23 × 94.124 g/mol= 0.214 grams | |||
* Make film1 with .214grams of phenol 10ml of water and 1 ml of gluataraldehyde and 1 gram of pooh | |||
* Make a stock solution of 10ml of water and .214 grams of phenol= 21.4 Molar of phenol = 10% reacts with OH groups on PVOH | |||
** Dilute from this solution to make 1%, 0.1% and 0.01% solution using m1v1=m2v2 equation | |||
**film 2-1%: 1ml of stock add to film with 10ml water, 1 gram of pva, 1ml of glutaraldehyde | |||
** film 3-.1%: .1ml of stock add to film with 10ml water, 1 gram of pva, 1 ml of glutaraldehyde | |||
**film 4-.01%: .01ml of stock add to film with 10 ml water, 1 gram of pva, 1 ml of glutaraldyde | |||
**Film 5- 7%: 7 ml of stock add to film with 10ml water 1 gram of pva, 1 ml of glutaraldehyde because 10% film failed with 10ml of water it evaporate off to quick | |||
**film 5- 1%: 1ml of stock add to film with 10ml water 1 gram of pva, 1ml of glutaraldehyde because 1% evaporated off to fast so made another one | |||
*stirred all contents of film on heat under fume hood to have them dissolve and this poured them into their respective dish | |||
*mass of phenol was weighed under fume hood toxic | |||
* determined best to use an Erlenmeyer flask instead of beaker for mixing | |||
'''Quaternary Ammonium Salt Purification''' | |||
# Turn off the heat on the round bottom flask containing the reaction and remove from the heating mantle. | |||
# Fill a beaker with 100 mL ethyl acetate. | |||
# Place on ice. | |||
# Add the product drop-wise | |||
# Filter and collect precipitate | |||
# reaction failed was unable to purify. will discuss on monday as to other way to attach a quaternary ammonium to pva with fox | |||
# reaction failed most likely due to the age of the starting material or decrease in strength of the leaving group Cl- compared to Br- for this reaction |
