Following is the molecular structure of Monosodium Acetylide (CAS NO.1066-26-8) is:
Preparation Products are Linalool --> Leaf Alcohol --> Vitamin A --> 1-Ethynyl-2-Methyl Penten-2-Ol --> Propiolic Acidd -->Chlorempenthrin .
When heated to 150°C it decomposes to form a gas which ignites spontaneously in air. The dry powder can ignite spontaneously if a large surface area is exposed to air (e.g. on a filter paper). When heated to decomposition it emits toxic fumes of Na2O. See also ACETYLIDES.

First Aid Measures:
Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
Skin: Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Ingestion: Get medical aid. Wash mouth out with water.
Inhalation: Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Handling and Storage:
Handling: Use spark-proof tools and explosion proof equipment. Avoid breathing dust, vapor, mist, or gas. Avoid contact with skin and eyes. Use and store under nitrogen. Do not allow contact with water.
Storage: Keep away from sources of ignition. Keep refrigerated. (Store below 4°C/39°F.) Store in a tightly closed container. Store in a dry area. Flammables-area. Keep away from acidic, alkaline, combustible and oxidizing materials.
