Make Cannabis Oil .... the choice of Solvent

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.

You can find this number tablespoon in the Chemical Substance Index: http://www.cas.org/

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
