What solvent
to produce oil?
For the manufacture of cannabis oil, many solvents are
used.
Before choosing a solvent, it should be borne in mind
that our manufacture a DRUG to be used, absorbed by sick people who trust. must
work as a professional, the amateur must be outlawed
It is our responsibility to develop a quality product,
to proceed with the utmost care. Should therefore be selected appropriate
materials! The quality of the finished product shall be equal to the quality of
the worst ingredient.
Be certain than the right product is used: several totally
different products can have the same trade name (danger of confusion) only guaranteed
when a trade name is given, always associate the No. CAS International
The C.A.S (Chemical Abstract Service) is an identifier
determined by computer. The algorithm identifies structural diagrams and
automatically allocates a CAS unique to each chemical entity (molecule, mixture
of isomers, industrial product).
This issue is divided into three parts, separated by
dashes. It is therefore of the form: YYYYYY-XX-X with Y: 3 to 6 digits.
Given the complexity of chemical nomenclature and the
possibility to identify a substance by several names, CAS number identifies the
chemical species unambiguously.
Naphtha
The Naphtha: petroleum, which is a generic name for a
mixture of compounds boiling variable (140 to 400 ° F) aliphatic alkanes and
paraffins used as paint thinner. Naphtha
sold in drugstores is a technical product containing impurities
To be avoided as such
Petroleum
ether
CAS Number 101316-46-5
Petroleum ether is refined naphtha with a boiling
point are known, it consists of a mixture of aliphatic alkanes (eg pentane,
hexane etc. ...)
One can easily find three grades of petroleum ether
(Grade: pure, with analysis report)
A-fraction distilled between 90 and 220 °F (the most
interesting for oil)
B- Fraction distilled between 220 and 250 ° F
C-Fraction distilled between 250 and 300 ° F
Advantage: chlorophyll is insoluble
Disadvantages: smell residual oil in low concentration
(an odorless oil is a guarantee of complete removal of the solvent)
This is probably the product that is used for Simpson
oil, medical grade
Hexane
CAS Number 110-54-3
Hexane is a constituent of petroleum ether, it is a
pure product with stable and defined physico-chemical characteristics (specific
boiling point)
Advantage:
pure product
Disadvantages:
very expensive
Ethyl alcohol
CAS Number 64-17-5
The most common solvents!
However, there are a wide variety of qualities (from
vodka .. until absolute alcohol)
It is difficult to obtain absolute alcohol (99%) it
absorbs water from the air to form a stable mixture 96%
Vodka (50%) is not suitable .. it contains too much
water and requires heat above 100 degrees to eliminate (degradation CBD)
Warning: alcohol for disinfection same undenatured is
dosed at 70% (to prevent coagulation of proteins)
Denatured alcohol by means of sulfuric ether is
dangerous: in addition to its characteristic odor is unstable and degrades
explosive peroxides hightly hepatotoxic
Advantages: non-toxic trough levels, relatively easy
to obtain
Disadvantage: chlorophylls dissolved, giving a dark
green color and a special flavor to the oil.
Isopropyl
alcohol
CAS Number 67-63-0
Identical to ethyl alcohol Features
Used for disinfection (70%)
Undenatured
Butane
Lighter gas,
Used only for very small quantities (some grams of raw
material)
EXPLOSIVE!
Advantage: no evaporation to make
Disadvantage : obligation to work outside, Explosive,
heavier than air
Coconut Oil
CAS Number 8001-31-8
Used as an extraction solvent, it does not allow high
concentration, concentration is impossible, because there is no evatoration
This is the ideal vehicle to dilute the oil extracted
by other methods, and allow a constant dosage of active ingredients
Corn oil
CAS Number
8001-30-7
As for
coconut oil
