Section 5 - FIRE FIGHTING MEASURES
General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. Combustible liquid.
Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas. Containers may explode when heated.
Runoff from fire control or dilution water may cause pollution.
Extinguishing Media:
In case of fire, use water, dry chemical, chemical foam, or alcohol-resistant foam. Use water spray to cool fire-exposed containers.

Section 6 - ACCIDENTAL RELEASE MEASURES
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, observing precautions in the Protective Equipment section. Remove all sources of ignition. Use a spark-proof tool. Provide ventilation.
Place under an inert atmosphere.

---

Section 7 - HANDLING and STORAGE
Handling:
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use only in a well-ventilated area. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Keep away from heat, sparks and flame. Avoid ingestion and inhalation. Store protected from light. Handle under an inert atmosphere. Store protected from air. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
Storage:
Keep away from sources of ignition. Keep container closed when not in use. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Do not expose to air. Store protected from light. Store under an inert atmosphere.

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
Engineering Controls:
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use process enclosure, local exhaust ventilation, or other engineering controls to control airborne levels.
Exposure Limits CAS# 94089-02-8: Personal Protective Equipment Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to prevent skin exposure.
Respirators:
Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.

  通过改变关键咖啡气味呋喃-2-基甲硫醇的结构基序合成的巯基呋喃和巯基噻吩的同源系列中的结构-气味关联

  摘要：

  呋喃-2-基甲硫醇（2-糠硫醇； 2-FFT，1）是众所周知的烘烤和磨碎咖啡中的主要气味剂，先前还被广泛用于肉类，面包和烘焙等热处理食品中芝麻籽。其独特的咖啡香气质量非常低浓度引起，而事实上，呈现出类似的结构，只有极少数的化合物先前已在食品中描述使1结构-气味活性研究的合适人选。为了深入了解在低浓度下会发出类似咖啡的气味的结构特征，合成了46种杂环硫醇和硫醚，其中32种首次合成，并确定了它们的气味质量和气味阈值。巯基向3位的移动保持了咖啡样的香气，但是导致了气味阈值的增加。由于碳侧链的延长，硫醇基团与呋喃环的分离导致咖啡味气味的损失，并且还导致气味阈值的增加，尤其是对于ω-（呋喃-2-基）烷烃-在侧链中具有六个或七个碳原子的1-硫醇。呋喃环被噻吩环取代对大多数所研究化合物的气味特性没有显着影响，但是新合成的长链1-（呋喃-2-基）-和1-（噻吩-2-基）烷烃-1-硫醇引发了令人兴奋的百香果
