Xylene,..substitute??? WTF!! | Bookmark | ||||||
Have any bees ever heard of this or have any idea what the hell it is?? http://www.sigmaaldrich.com/Area_of_Inte Xylene Substitute is a newly developed Xylene-free clearing agent. Unlike Xylene or Citrus Limonene, it has no overpowering odor. Use Xylene Substitute without any of the health concerns of Xylene. Xylene Substitute is completely soluble in alcohol and has no effect on most laboratory plastics. It is also less flammable than Xylene. This Xylene replacement gives you excellent clinical results. Xylene Substitute evaporates quickly and is ideal for use with all Trichrome procedures. It gives consistent results with excellent clarity. Xylene Substitute effectively deparaffinizes and eliminates residual chemicals. Xylene Substitute is convenient and is less expensive than Xylene. Most users will not require disposal by second party waste haulers. Costly distillation becomes unnecessary. -S/D Sorry,I had my tang all toungled behind my eye teeth, and I couldn't see what I was saying. |

No safety or tech data on the site yet. If it is the same as propar, it is propylene glycol ether. HRH The Prince of Wales and Earl of Chester, Knight of the Garter, Rogerer of Servant Girls |

I knew it | Bookmark | ||||||
Ya know, I almost started a thread on Xylene substitutes. It is comprised of isoalkenes, and is used in the histology industry. I think the name is a little deceptive however. It is used as a clearing agent to clear and remove parrafin from histology slides during the staining process, which xylene was the solvent of choice for many years. Xylene subsitute as far as I know only replaces xylene in the histology industry. I do not believe it can replace xylene in any other applications however. I am not a chemist, though. I know I can get the MSDS tommorow, I will get it to y'all.... Unipolar Mania, It's good for life... |

Sorry, in my first post I stated isoalkenes, I meant isoalkanes. Anyway here is the MSDS.... I will leave it to the chemists to decide if this can actually be used as a xylene sub in clandestine chemistry. Good luck.... 1. Identification of the substance/preparation and of the company Trade name HistoSolve, Xylene Substitute Manufacturer/Supplier Thermo Shandon, Inc. 171 Industry Drive Pittsburgh, PA 15275 USA Email: thermoshandon@thermoshandon.com Internet: http://www.thermoshandon.com Phone: 412-788-1133 Fax: 412-788-1138 Emergency telephone Chem-Tel, Inc. 1-800-255-3924 2. Composition/Information on ingredients Ingredients % w/w CAS no. Classification Exposure limits 100% Isoalkanes C9-12 90622-57-4 R10 Xn;R65 - 3. Hazards identification Particular information pertaining specific risk for human and environment: Flammable and harmful hydrocarbons with long-term effects. 4. First-aid measures General If any symptoms occur: Seek medical advice. Show this Safety Data Sheet to a physician or emergency ward. Eye contact Flush with water or physiological salt water for 15 minutes. Remember to remove contact lenses. If irritation persists: seek medical advice. Continue flushing on the way. Skin contact Remove contaminated clothing and wash skin with water and mild soap. Flush 15 minutes with water. Rub the skin with a hand lotion. Inhalation Remove to fresh air. Keep at rest. If symptoms persists: seek medical advice. Administer oxygen or artificial respiration as needed. Ingestion Rinse mouth and drink plenty water. Do not provoke vomiting. If vomiting occurs, bend over and keep head down to avoid vomit in the lungs. Burns Flush with water until pain ceases. 5. Fire-fighting measures Flammability Combustible liquid. Extinguishing media - suitable Use dry chemical or foam. Extinguishing media - NOT suitable - Special risks in a fire situation Application of water fog/spray will aid in keeping fire-exposed materials cool. In case of fire the product may form hazardous decomposition product such as oxides of carbon. Protective equipment When extinguishing fires use self-contained breathing apparatus. Additional information Remove containers if possible. 6. Accidental release measures Personal precautions Provide for sufficient ventilation/respiratory protection. See protective equipment listed in section 8. Remove sources of ignition. Environmental precautions Do not empty into drains. If the product contaminates lakes, rivers or sewages, inform appropriate authorities in accordance with local regulations. Methods for cleaning up/collecting Sweep up with a non flammable absorbent material. Flush with water. Further handling of spillage: see section 13. 7. Handling and storage Safe handling See section 8. Safe storage At room temperature and well ventilated and away from strong oxidizers. Keep container tightly closed when not in use. Store in a flammable liquid storage area. 8. Exposure controls and personal protection Engineering measures (prevention of worker exposure) Avoid breathing of vapors and contact with skin, eyes and clothes. Provide adequate ventilation. There shall be access to water. Wash with water and soap after work. Flammable, do not use near fire or sparks. Do not smoke. Exposure limits: See section 2. Personal protective equipment Eye protection: Wear safety goggles when risk of splashing. Skin protection: Use gloves of nitrile rubber. Respiratory protection: In case of badly ventilated areas use an approved mask with a gas filter: A when risk of inhaling vapours. 9.

Stability and reactivity Stability Vapors can be ignited by a spark, a hot surface or a glow. Vapors are heavier than air and can travel along the ground to an ignition source and flash back to vapor source. Conditions to avoid Sources of ignition, such as heat, sparks, and flames. Materials to avoid Strong oxidizing agents. Hazardous decomposition products Combustion may produce oxides of carbon. 11. Toxicological information Routes of exposure: May be absorbed by inhalation and ingestion. Acute toxicity: Eyes Splashes and high concentrations of vapors may cause irritation with redness. Skin May cause irritation with redness. Inhalation Inhalation of vapors in high concentrations may irritate mucous membranes and induce headache, nausea, vomiting, dizziness and unconcsiousness. Ingestion May irritate the gastrointestinal tract and cause symptoms as mentioned under inhalation. Hydrocarbons are harmful and may cause lung damage if swallowed. Be aware that symptoms (dyspnea) can develop several hours after exposure.

Not so sure | Bookmark | ||||||
There are several xylene substitutes. Main function is to remove parafins as you say. Seem to be 3 types: 1. limonenes (orange oil etc) 2. long chain aliphatics 3. propylene glycol ether Not sure which this is. A free gallon though...(even a tiny US one)...not to be missed surely?
