(eBook - PDF - Chemistry) Methamphetamine Synthesis

Pseudoephedrine, active ingredient of Sudafed®, has longbeen the most popular nasal decongestant in the United Statesdue to its effectiveness and relatively mild side effects [1]. Inrecent years it has become increasingly difficult to obtainpsuedoephedine in many states because of its use as aprecursor for the illegal drug N-methylamphetamine (alsoknown under various names including crystal meth, meth, ice,etc.)[1,2]. While in the past many stores were able to sellpseudoephedrine, new laws in the United States haverestricted sales to pharmacies, with the medicine kept behindthe counter. The pharmacies require signatures andexamination of government issued ID in order to purchasepseudoephedrine. Because the hours of availability of suchpharmacies are often limited, it would be of great interest tohave a simple synthesis of pseudoephedrine from reagentswhich can be more readily procured.

A completely different procedure of synthesis uses the of with , both of which are currently chemicals (as are pseudoephedrine and ephedrine). The reaction requires a catalyst that acts as a reducing agent, such as or platinum dioxide, also known as . This was once the preferred method of production by in , until DEA restrictions on the chemicals made the process difficult. Other less common methods use other means of hydrogenation, such as in the presence of a .

Reduction of Ephedrine to Methamphetamine Using Hypophosphorus ..

Most methods of illicit production involve of the group on the or molecule. Methamphetamine is most structurally similar to and amphetamine. The most common method for small-scale methamphetamine labs in the United States is primarily called the "Red, White, and Blue Process", which involves red , or (white), and (which is technically a purple color in elemental form), from which is formed. In Australia, criminal groups have been known to substitute "red" phosphorus with either hypophosphorous acid or phosphorous acid. This is a hazardous process for amateur chemists, because gas, a side-product from hydroiodic acid production, is extremely toxic to inhale.

Topics: Breaking Bad, DEA, Howard Dean, Methamphetamine, you could synthesize with 30 gallons of methylamine using the P2P meth recipe.

is produced for each pound of meth cooked in crystal meth synthesis.

Tablets may contain up to 40 mg of active drug. The free base constitutes 80 % of the hydrochloride salt. The retail purity of methamphetamines in 2011 ranged from 16 % (Estonia and Denmark) to 82 % (Turkey) in European countries reporting information (). In Europe, the most common are caffeine, glucose and other sugars, less commonly ephedrine or ketamine. Methamphetamine has been seen as an in ecstasy tablets.

Crystal Meth – The “Chemical Star of the Show” At the beginning, Walter pursues synthesis using pseudoephedrine.

Ephedrine methamphetamine synthesis

Synthesis is relatively simple, but entails risk with flammable and corrosive chemicals, particularly the solvents used in extraction and purification; therefore, illicit production is often discovered by fires and explosions caused by the improper handling of volatile or flammable solvents. Most of the necessary chemicals are readily available in household products or cold or allergy medicines. When illicitly produced, methamphetamine is commonly made by the of or . The maximum conversion rate for ephedrine and pseudoephedrine is 92%, although typically, illicit methamphetamine laboratories convert at a rate of 50% to 75%.

was first made in 1887 in Germany and methamphetamine, more potent and easy to make, was developed in Japan in 1919; it went into wide use during the to keep the troops awake. The japanese kamikazes use it before their suicidal missions.
In 1950's, amphetamine was prescribed as a or to cure .
In 1980, (phenyl-2-propanone, a precursor for amphetamine) was placed under federal control, so was discovered that, using the , readily available, you can obtain a drug twice as strong as the -derived one, and it is not amphetamine, methamphetamine indeed.
