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. Users may feel like they are instantly transported to another universe and feel outside of their body known as “depersonalization. Under the negative pressure of 10KPa-15KPa (A), DMT can form steam (liquid phase small particles in gas) at 240 ℃ due to low density, effectively separate dihydroxyl terephthalate and dihydroxyl terephthalate oligomer in the kettle residue, and output from the gas phase of an evaporator. The invention provides a method and equipment for obtaining DMT from distillation still residue, which comprises the following steps: negative pressure evaporation: carrying out negative pressure evaporation on the distillation kettle residue by adopting a film evaporator, and condensing and separating a gas phase to obtain DMT; the recovery liquid is obtained by carrying out continuous alcoholysis and ester exchange on the waste polyester raw material, the alcoholysis agent and the alcoholysis catalyst in a molten state to synthesize an ester exchange product; carrying out DMT crystallization on the ester exchange product, and washing the DMT crystallization with methanol to obtain a DMT filter cake; the DMT filter cake is purified by a short-flow rectification system under the vacuum of 6. If the root bark is un-powdered, use a coffee grinder or blender to shred the bark into fine pieces.
Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed. It has been designed to balance simplicity, accessibility, and product quality while prioritizing user safety. However, there is no guarantee on a standard experience from taking DMT; 2 people may have entirely different reactions. discloses that DMT is purified in two steps, crude extraction: cooling the ester exchange product to separate out DMT crystal, and filtering to obtain DMT filter cake; fine extraction: and rectifying and purifying the DMT filter cake to obtain pure DMT. Keep reading, inform yourself, take safety precautions, don't throw anything away before you're done with your extraction and don't consume anything you are not sure its clean.In the present embodiment, the method for recovering waste polyester by continuous alcoholysis disclosed in chinese patent application No. Basifying the solution to a pH of 13 in the following steps allows it to be extracted from the polar solution (i.
Unless someone is currently under the influence of the drug, spotting DMT symptoms and warning signs can be difficult. N,N-Dimethyltryptamine ( DMT) is a psychedelic compound that is found naturally in some plants and animals.
If the naphtha solution is left at room temperature before the DMT is separated from it, the DMT can potentially dissolve back into the naphtha. An hour after smoking DMT, the user should be symptom free, although they may feel some residual effects in the following hour. Within 5 minutes of taking DMT, users may experience increased blood pressure, rapid heartbeat, and dilated pupils. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or terminal that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or terminal.
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.It should be noted that, although the above embodiments have been described herein, the invention is not limited thereto. For the following steps, take appropriate safety precautions and wear safety goggles, a mask, and chemical resistant gloves. 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.
