discloses a continuous alcoholysis recovery method for waste polyester, which adopts the continuous feeding and continuous alcoholysis process to perform homogeneous alcoholysis on materials in a molten state, the required alcoholysis time is short, more than two alcoholysis kettles are connected in series to perform continuous alcoholysis, and the product quality of an alcoholysate is stable. One important direction of chemical recovery is to alcoholyze the waste polyester with Ethylene Glycol (EG) to produce dihydroxy terephthalate (BHET) or oligomers, then perform transesterification in methanol to produce dimethyl terephthalate (DMT) and ethylene glycol, obtain pure DMT by purification, and use the pure DMT as raw material for polyester production, and use the purified methanol and ethylene glycol in the reaction system to realize the recycling of the waste polyester.
In the recovery method, as the materials are subjected to homogeneous alcoholysis in a molten state, and alcoholysates directly enter ester exchange, the components of ester exchange products are complex, including the components, reactants and solvents in the steps of feeding, alcoholysis and ester exchange, so that the kettle residue after DMT rectification contains intermediate products (dihydroxy terephthalate and dihydroxy terephthalate oligomers) and DMT which are difficult to separate. One report of a 24-year-old man who inhaled a smokable powder made of DMT-containing plants developed, “a complex delusional spiritual belief system and was pursuing enlightenment,” which later led to hospitalization from presenting positive symptoms of schizophrenia. In the method, only one common distillation device is arranged behind the alcoholysis kettle and the ester exchange kettle to ensure the recovery of EG and methanol, and the recovery rate is low. appear that the addition of MeOH and NH 4OH aq has very little effect on the rate of the reaction of DMT with DCM.When inhaled, smoked or injected, the effects are short: about five to twenty minutes, when orally ingested, effects last three to five hours. If the root bark is un-powdered, use a coffee grinder or blender to shred the bark into fine pieces. DMT symptoms and warning signs are obvious if the person is currently under the influence of the drug, as they may be incapacitated. Common reports from people who had a near death experience include, “a bright light, a sense of detachment from the body, feelings of security and warmth and encounters with spiritual beings such as angels. Erratum: Internet method for the extraction of N,N-dimethyltryptamine from Mimosa hostilis roots: Does it really extract dimethyltryptamine?
The invention adopts a film evaporation mode under negative pressure to separate the dihydroxy terephthalate, dihydroxy terephthalate oligomer and DMT in the kettle residue, so that more than 80 percent of DMT in the kettle residue is effectively recovered.DMT content (Schultes 1977) while the inner root bark has been reported to contain up to 2% in active alkaloids. Dayna Smith-Slade is a nationally certified Master Addictions Counselor (MAC), licensed Substance Abuse Professional (SAP), and Substance Abuse Expert (SAE) with over 29 of hands-on experience in the addiction field. When sodium hydroxide is added to the glass jar, it must be done gradually to prevent the strong exothermic (heat-releasing) reaction that can crack the container. It is grown as far north as southern Mexico (Oaxaca and Chiapas), as well as El Salvador, Honduras, Panama, Colombia and Venezuela.
DMT symptoms and warning signs are obvious if someone is currently under the influence of the drug; they may be difficult to spot once the user is no longer tripping, however. Therefore, based on the innovative concepts of the present invention, the technical solutions of the present invention can be directly or indirectly applied to other related technical fields by making changes and modifications to the embodiments described herein, or by using equivalent structures or equivalent processes performed in the content of the present specification and the attached drawings, which are included in the scope of the present invention.In the present embodiment, the method for recovering waste polyester by continuous alcoholysis disclosed in chinese patent application No.
Decomposing the cell membrane allows for higher absorption of DMT from the plant matter in the following steps. Reaction of DMT ( 1) with 9:1 DCM/MeOH with 1% NH 4OH aq to produce 10 monitored by 1H NMR over time. Original Assignee Ivan Jiade Shanghai Environmental Protection Technology Co ltd Priority date (The priority date is an assumption and is not a legal conclusion.Users may feel like they are instantly transported to another universe and feel outside of their body known as “depersonalization. It can be handled safely but is harmful if it is inhaled, swallowed, or if the liquid is breathed into the lungs; it is also an irritant to the eyes and skin. The cut was superficial, but the psychotic/paranoid symptoms continued for 2 to 3 weeks, and he had to receive antipsychotic treatment for 1 year. He believed that he could read minds, interact with aliens, and control people and events by adopting different body postures.
