Title: Melting Point
Post by: WizardX on June 18, 2004, 07:34:00 PM

d-Methamphetamine is 170-175 oC at ~95% purity. At 98% purity melting point is 174-175 oC.

Mixtures of the d & l isomers have different melting points to a single pure isomer.

Phenylisopropylmethylamine hydrochloride ; C10H15N.HCl  C6H5CH2CH(NHCH3)CH3.HCl reacts with HgCl2, and Phenylisopropylmethylamine freebase reacts with HAuCl4, and H2PtCl6 to form a precipitate metallic salt with characteristic melting point and crystal properties.

C6H5CH2CH(NH2CH3)CH3Cl : Phenylisopropylmethylamine hydrochloride salt (dl), melting point between 131-135 degC, plate-shaped crystals.

C6H5CH2CH(NH2CH3)CH3ClHgCl2 : Phenylisopropylmethylamine hydrochloride mercuric salt (dl), melting point between 128-130 degC, flat needle crystals.   

C6H5CH2CH(NH2CH3)CH3ClAuCl3 : Phenylisopropylmethylamine hydrochloride aurate salt (dl), melting point between 108-109 degC, flat needle crystals.

(C6H5CH2CH(NH2CH3)CH3Cl)2PtCl4 : Phenylisopropylmethylamine hydrochloride platinic salt (dl), melting point 205 degC, orange-yellow prism crystals.
