KAA - Chemistry for Embalmers - Week 2
AROMATIC ALCOHOLS
2 types: aromatic alcohols and phenols
full oxidation
as the skipping of one step in the oxidation process; going from an alcohol to an organic acid. results in CO2 and H2O as the products no matter what you started with, CO2 and H2O are the products
chloromethane / methyl chloride
class = Halide CH3Cl
trichloromethane / chloroform
class = Halide CHCl3 Highly flammable, anasthetic no longer used in US
tetrachloromethane/carbon tetrachloride
class = Halide every H in methane is replaced with a Cl halogen. CCl4 was used as a stain remover in dry cleaning before determined to be carcinogenic
dichloromethane/ methylene chloride
class =Halide CH2Cl2
skeleton structure
does not indicate the specific radical only that there is a radical present
partial oxidation of ethanol/ethyl alcohol/grain alcohol
ethanal/acetaldehyde as product
full oxidation of ethanol/ethyl alcohol/grain alcohol
ethanoic acid/acetic acid as product
partial oxidation of ethanal/acetaldehyde
ethanoic acid/acetic acid as product
Alcohols
hydrocarbons in which a hydrogen atom is replaced by a Hydroxyl group (-OH) Functional group OH General Formula R-OH will neutralize an organic acid because it acts as a base
partial oxidation of methanol/methyl alcohol/wood alcohol
methanal/formaldehyde as product
full oxidation of methanol/methyl alcohol/wood alcohol
methanoic acid/formic acid as product
partial oxidation of methanal/formaldehyde
methanoic acid/formic acid as product
halogenation
replacing a hydrogen with a halogen
ISOPROPYL ALCOHOL / RUBBING ALCOHOL
secondary alcohol Molecular formula is: C3H8O Line Formula is: CH3CHOHCH3 in the structural formula the OH is in the middle with a methyl radical on each side
Uses/characteristics for Ethanol
used in the preparation of ether and chloroform partial oxidation of ethanol gives you acetaldehyde / ethanal the type of alcohol that we drink now being used as an alternative to gasoline
DECANOL / DECYL ALCOHOL
Molecular formula is: C10H22O Line Formula is:C10H21OH
complete oxidation of ethanol/ethyl alcohol/grain alcohol
CO2 and H2O as product
complete oxidation of methanol/methyl alcohol/wood alcohol
CO2 and H2O as product
partial oxidation of methanoic acid/formic acid
CO2 and H2O as product
Classifications of Alcohols
MONOHYDROXY ALCOHOLS DIHYDROXY ALCOHOLS TRIHYDROXY ALCOHOLS POLYHYDROXY ALCOHOLS
METHANOL / METHYL ALCOHOL / WOOD ALCOHOL
Molecular Formula is CH4O Line Formula is CH3OH Structural formula is: methanol derivative of methane, result of methane undergoing oxidation
ETHANOL / ETHYL ALCOHOL / GRAIN ALCOHOL
Molecular formula is: C2H6O Line Formula is: C2H5OH prepared by the fermentation of sugar (glucose- C6H12O6) by the enzymes found in yeast; this process is called alcoholic fermentation reaction since alcohol is one of the products C6H12O6 —yeast enzymes——> 2C2H5OH + 2CO2
PROPANOL / PROPYL ALCOHOL
Molecular formula is: C3H8O Line Formula is: C3H7OH
BUTANOL / BUTYL ALCOHOL
Molecular formula is: C4H10O Line Formula is:C4H8OH
PENTANOL / PENTYL ALCOHOL
Molecular formula is: C5H12O Line Formula is:C5H11OH
HEXANOL / HEXYL ALCOHOL
Molecular formula is: C6H14O Line Formula is:C6H13OH
PHENOL / CARBOLIC ACID
Molecular formula is: C6H6O Line Formula is: C6H5OH named carbolic acid because when it is put in solution it ionizes as an acid would. highly poisonous is a powerful germicide , preservative , disinfectant, fungicide, cautery agent, reducing agent, drying agent and great bleaching agent RA: An antiseptic/disinfectant employed to dry moist tissues and to bleach discolored tissues all are a type of aromatic alcohol
HEPTANOL / HEPTYL ALCOHOL
Molecular formula is: C7H16O Line Formula is:C7H15OH
OCTANOL / OCTYL ALCOHOL
Molecular formula is: C8H18O Line Formula is:C8H17OH
NONANOL / NONYL ALCOHOL
Molecular formula is: C9H20O Line Formula is:C9H19OH
Phenols
Occur when an (-OH) group is substituted directly onto the benzene ring, it is the resulting product In a general sense means any benzene derivative with one or more (-OH) groups in direct combination with the benzene ring.
Aromatic Alcohols
Occur when an (-OH) group is substituted onto the side chain of an aromatic hydrocarbon the placement of the (-OH) is "once removed" from the carbon ring it is not directly attached to a carbon that is part of the ring; it is attached to a carbon that is attached to the carbon ring.
Organic Chemistry Neutralization
Organic Acid + Alcohol → Ester + Water
OXIDATION PROCESS
Partially oxidizing any Primary Alcohol will give you an Aldehyde Fully oxidizing any Primary Alcohol will give you an Organic Acid Partially oxidizing any Secondary Alcohol will give you a Ketone Partially oxidizing an Aldehyde will give you an Organic Acid Completely oxidizing an Alcohol (or any organic substance) will give you CO2 + H2O
alcohol isomers
Propanol / Propyl Alcohol and Isopropyl Alcohol because they have the same molecular formula but different structural formulas
SORBITOL
a POLYHYDROXY ALCOHOL Molecular formula is: C6H14O6 Line Formula is: C6H8(OH)6 Sugars are a derivative of listed on product labels as a sweetener used in the synthesis of Vitamin C. Isomers of (Mannitol and Dulcitol) are used in embalming fluids as Humectants or Wetting Agents.
GLYCOL / ETHYLENE GLYCOL
a dihydroxy alcohol Molecular formula is: C2H6O2 Line Formula is: C2H4(OH)2 is a coolant or antifreeze. For embalming purposes, it is a Humectant or Wetting Agent thick colorless liquid with very little odor readily soluble in water can be used in conjunction with other humectants or on its own
Uses/characteristics for Methanol
a good solvent for organic compounds. used as certain types of gas, antifreeze, varnishes and shellacs. It is severely poisonous; it causes blindness and death. Basically if you ingest it you embalm yourself. used in the production of Formaldehyde / Methanal; by partially oxidizing (CH3OH) you get Methanal (HCHO)
GLYCEROL / GLYCERIN
a trihydroxy alcohol Molecular formula is: C3H8O3 Line Formula is: C3H5(OH)3 softener that is used in hand lotions For embalming purposes it is a Humectant or Wetting Agent as well as a solvent for high index embalming fluids. a syrupy, colorless liquid obtained from fats or oils as a by-product of the manufacturing of soaps and fatty acids used as a vehicle for some cosmetics
TERTIARY ALCOHOLS
alcohols in which the hydroxyl (-OH) group is attached to a carbon that is attached to three (3) other carbons the (-OH) is attached to a carbon that has three other radicals attached to it
SECONDARY ALCOHOLS
alcohols in which the hydroxyl (-OH) group is attached to a carbon that is attached to two (2) other carbons the (-OH) is attached to a carbon that has two other radicals attached to it
PRIMARY ALCOHOLS
alcohols where the (-OH) is attached to the carbon located at the end of the carbon chain, either the first or last carbon in the chain Since the radical was once a saturated hydrocarbon that had the suffix of ANE you drop the E and change it to OL. eg Methane becomes Methanol OR name the radical; Methyl, Ethyl, Propyl etc, then add to word alcohol. eg Methyl alcohol
POLYHYDROXY ALCOHOLS
alcohols which contain many (4 or more) (-OH) or Hydroxyl groups
MONOHYDROXY ALCOHOLS
alcohols which contain one (1) (-OH) or Hydroxyl group divided into three (3) groups. PRIMARY ALCOHOLS - 1° SECONDARY ALCOHOLS - 2° TERTIARY ALCOHOLS - 3°
TRIHYDROXY ALCOHOLS
alcohols which contain three (3) (-OH) or Hydroxyl groups
DIHYDROXY ALCOHOLS
alcohols which contain two (2) (-OH) or Hydroxyl groups
alkyl halide
an aliphalic hydrocarbon with one or more halogens attached or an aliphalic hydrocarbon that has undergone halogenation
