We believe you. Now can somebody post the *recipe* The following is the answer I received when I asked this question in the nz.general newsgroup. New Zealand has a fair number of homebake users as I guess it is not so easy to import other illicit opiates. "Homebake refers to heroin manufactured illicitly. It is usually manufactured crudely, on a small scale, on an `as required' basis, although larger scale and more sophisticated setups, which are more laboratory-like and give a more refined product, are occasionally found. There are two common methods of manufacture. One uses codeine-based pharmaceuticals (typically tablets containing codeine and paracetamol). The codeine is extracted and converted to morphine. The morphine is then converted to diacetylmorphine (heroin) using acetyl chloride or acetic anhydride (usually the latter). The other method uses morphine tablets (available in sustained-release form). The morphine is extracted and converted to heroin as above. Most medical professionals are well aware of this potential use for codeine-based pharmaceuticals, and chemical suppliers are now more aware of of this use for chemicals such as acetic anhydride. However, drug misusers still seem able to obtain these products as well as morphine tablets." Neil Hunt =============================================================== From: dmurphy3@aol.com (DMurphy3) Subject: Homebake: Codeine to Morphine Date: 1995/10/26 newsgroups: alt.drugs.chemistry This came from Forensic Science International, K. Bedford, S. Nolan, R. Onrust, and J. Siegers, v34, 1987, pp 197-204. Title is "The Illicit Preparation of Morphine and Heroin from Pharmaceutical Products Containing Codeine: 'Homebake' Laboratories in New Zealand". "The O-demethylation of codeine to yield morphine has been accomplished using a very simple method based on pyridine hydrochloride. This reagent was introduced to opiate chemistry by Rapoport and Bonner (J. Amer. Chem. Soc., v73, 1951, p5485) and was first applied to the conversion of codeine to morphine by Rapoport, et al. (J. Am. Chem. Soc., v73, 1951, p5900). The reaction was carried out under nitrogen at 220 C because morphine is prone to decomposition or oxidation reactions at elevated temperatures and the nitrogen atmosphere prevents or reduces these. It also limits the access of moisture which reduces the yield." Following is the method used, with some elaboration: 1. Crush sufficient pills to yield 2 g of codeine and mix with distilled water. Filter with a vacuum funnel to remove insolubles and add to a separatory funnel. Add NaOH solution to make the solution pH 12. Extract twice with chlorofrom (2x25 mL). This will be the bottom layer. Discard the water layer, which contains the aspirin or acetominophen) and evaporate the chloroform layer to dryness under gentle heat. The result is codeine base, a white crystalline powder. 2. Combine 20 mL pyridine and 25 mL conc. HCl in a beaker and heat strongly to 190 C to drive off any water. Cover and cool rapidly to obtain a white waxy material. This should be stored in a sealed container in the freezer if not to be used immediately. 3. The reaction is carried out in a glass boiling tube (here one could use a large ignition type test tube) which is sealed on one end. This should be oven dried before use. Then 3.5 g of the pyridine salt is added to the tube and this is then heated until it melts and for a few minutes more to drive off any moisture. Add 1.5 g of the base and seal the tube with a rubber stopper covered with a filter paper. Heat until the mixture begins to fume and continue until the mixture develops a reddish-orange color and becomes noticeably more viscous, typically 6-12 minutes. Pour this into a 500 mL sep funnel and make the volume up to 100 mL with distilled water. Add 10% NaOH until strongly basic. The contents will become milky brown and then clear brown as the solution is made basic. When this point is reached, extract with 20 mL chloroform. This will contain any unreacted codeine (up to 70%) and may be saved for recovery if desired. The morphine is in the water layer. Put the water layer in a beaker and carefully adjust the pH with HCl to pH 9 using a narrow range pHydronium paper. This is critical. Rapidly filter using two layers of paper (here one could use a paper designed for very fine crystals) and a vacuum flask/funnel as in step 1. A very fine brown powder will collect on the paper. This is unwanted byproducts and should be discarded. Pour the filtrate into a clean beaker and, while carefully adjusting the pH to 8.5, vigorously rubbing the inside of the beaker with a "seeding stick" (here the authors mention that a split wooden peg is sometimes used in the home labs in NZ; a glass stirring rod would be preferable). Crystals should begin to form. These are allowed to settle for at least 5 minutes and then are recovered by vacuum filtering to recover the morphine as a beige to dark brown product. The authors report some perp's claims of 50% conversion from the codeine, but say they obtained 30% typically, and further state that this is about what one would expect from Rapoport's paper. Purity of up to 92% with a more typical purity in the 80% range was reported by the authors using this method.
