NEO PENTANOIC ACID

Neo Pentanoic Acid
This Product Safety Summary document is a high-level summary intended to provide the general public with an overview of product safety information on this chemical substance. It is not intended to provide emergency response, medical or treatment information, or to provide a discussion of all safety and health information. This document is not intended to replace the Material Safety Data Sheet. Warnings and handling precautions provided below are not intended to replace or supersede manufacturers' instructions and warning for their consumer products which may contain this chemical substance.
1. Chemical Identity
CAS No. 75-98-9 Neo Pentanoic Acid Synonyms: Pivalic Acid, Trimethyl acetic acid,
2,2 Dimethylproprionic acid
2. Product Uses
Neo Pentanoic Acid is used as an intermediate to make other chemical products such as chlorides, esters, and metal salts. It is not sold directly to the public for general consumer uses. Pivaloyl chloride is an intermediate for a large number of derivatives, e.g. agrochemicals, pharmaceuticals, and peroxides. The latter are used as polymerization initiators. Esters of neopentanoic acids (e.g. methylpivalate) are used in applications such as coatings. Metal salts can be used in applications such as paint driers or PVC stabilizers.
3. Physical / Chemical Properties
Neo Pentanoic Acid is a solid at room temperature with a relatively low vapor pressure, however elevated temperatures and mechanical action may form vapors, mist, or fumes. Material should be handled only with adequate ventilation and in areas where ignition sources have been removed (e.g. open flames, static electricity sources, unprotected light switches). The flash point for Neo Pentanoic Acid is approximately 140ºF />60ºC.
4. Health Information
Neo Pentanoic Acid has been adequately studied and is generally recognized to have low acute toxicity if ingested and moderate toxicity if breathed. Concentrations (above 25 mg/m3 ) in the air can cause eye, nose, throat, and lung irritation in humans. Repeated dermal exposure may cause skin irritation, dryness and cracking. Neo Pentanoic Acid is not regarded as a mutagen or carcinogen, and there is low concern for reproductive, developmental, or nervous system toxic effects.
5. Additional Hazard Information
Harmful if ingested or if fumes or vapors are breathed. Repeated dermal exposure may cause skin irritation, dryness, and cracking.
6. Food Contact Regulated Uses
Neo Pentanoic Acid is not claimed as compliant for food contact uses.
Product Safety Summary
Neo Pentanoic Acid

7. Environmental Information
Neo Pentanoic Acid is soluble in water and, if spilled, is expected to remain largely in water. If released to the environment, this material is not expected to cause short-term toxicity to fish or other aquatic organisms. Long-term effects (chronic aquatic toxicity) are not expected because of low toxicity and biodegradation that results in a low potential for chronic exposure to aquatic organisms (following, for example, an accidental spill). The intent, however, is to minimize any exposure to the environment from manufacturing and use activities.
8. Exposure Potential
Based on the uses for Neo Pentanoic Acid, the public could be exposed through:
Workplace exposure – This refers to potential exposure to Neo Pentanoic Acid in a manufacturing facility or through evaporation in various industrial applications. Generally, exposure to Neo Pentanoic Acid of personnel in manufacturing facilities is relatively low because the process, storage and handling operations are enclosed. The ExxonMobil exposure limit value is 25 mg/m3 per an 8- hour work day.
Consumer use of products containing Neo Pentanoic Acid – Neo Pentanoic Acid is not sold directly to the public for general consumer uses. It is primarily converted into other chemicals. As a result of its use in industrial chemical reactions, consumer exposure is highly unlikely. If exposure should occur, it is expected to be infrequent and of short duration.
Environmental releases – Chemical manufacturers are committed to operating in an environmentally responsible manner everywhere we do business. Our efforts are guided by in-depth scientific understanding of the environmental impact of our operations, as well as by the social and economic needs of the communities in which we operate. Industrial spills or releases are rare; however a spill may pose a significant flammability issue. Our operational improvement targets and plans are based on driving incidents with real environmental impact to zero and delivering superior environmental performance.
9. Manufacture of Product
Process – Neo Pentanoic acid is produced by reacting a branched olefin with carbon monoxide and water at elevated temperatures and pressures in the presence of an acid catalyst. Considerable measures are taken to prevent its release to the atmosphere. Processes and equipment for manufacture, transfer and storage are continuous and enclosed.
10. Risk Management
Workplace Risk Management - When using this chemical, make sure that there is adequate ventilation. If controls do not maintain air concentrations at a level which is adequate to protect worker health, an approved respirator may be appropriate. Always use chemical resistant gloves to protect your hands and skin and always wear eye protection such as chemical goggles. Do not eat, drink, or smoke where this chemical is handled, processed, or stored. Wash hands and skin following contact. If this chemical gets into your eyes, rinse eyes thoroughly for at least 15 minutes with tap water and seek medical attention. Please refer to the Safety Data Sheet.
Consumer Risk Management - This chemical is not sold directly to the public for general consumer uses. As a result of its use in industrial chemical reactions, consumer exposure is highly unlikely. If exposure should occur, it is expected to be infrequent and of short duration. Always follow

Product Safety Summary
Neo Pentanoic Acid manufacturers' instructions, warnings and handling precautions when using their products.The best way to prevent exposure to vapors is to work in well-ventilated areas.
11. Regulatory Information
Regulations may exist that govern the manufacture, sale, transportation, use and/or disposal of this chemical and may vary by city, state, country or geographic region. Additional helpful information may be found by consulting the relevant ExxonMobil Safety Data Sheet at:

12. Conclusion Statement
Neo Pentanoic Acid is a widely used chemical intermediate in the production of derivatives used in agrochemicals, pharmaceuticals, coatings and polymerization initiators.
Neo Pentanoic Acid can be harmful if ingested or if fumes or vapors are breathed. Repeated dermal exposure may cause skin irritation, dryness, and cracking.
Neo Pentanoic Acid does not cause adverse health or environmental effects at levels typically found in the workplace or environment.
Neo Pentanoic Acid is combustible and has a low vapor pressure. Use only with good ventilation and avoid all ignition sources.

Abstract
Four commercial neo acids (synthetic trialkylacetic acids) C5, C7, C10, and C13 are synthesized employing an olefin, carbon monoxide, and acidic catalyst and possess the hindered neo configuration around the alpha carbon. Esterification using simple alcohols and polyols, and preparation of peroxyesters and metal salts using neo acids as well as toxicity,LD 50 values of the acids, are discussed. Hydrolytic stability of the esters, and possible end use applications are described.

Neo Pentanoic Acid
Typical reaction products include specialty metal salts, acid chlorides and esters used as intermediates in a large variety of end uses.
