Mono pentaerythritol (PETP) isan odourless white crystalline material. It is a polyhydric alcohol containing four primary hydroxyl groups. It dissolves freely in hot water, moderately easily in cold water and is slightly soluble in alcohol and other organic liquids.
Mono pentaerythritol is produced from the aldol condensation of formaldehyde and acetaldehyde. The resulting aldehyde undergoes a cross-Cannizzaro reaction to reduce one molecule of pentaerythritose to pentaerythritol. The raw pentaerythritol is then separated out, dissolved, subjected to high temperature acid hydrolysis and purified in an active carbon bed before being concentrated and crystallised.
PETP is a versatile chemical building block for the preparation of many polyfunctionalized compounds.

Applications of Mono Pentaerythritol
Mono pentaerythritol is primarily used as a starting material for polymer production. It is employed in the manufacture of alkyd resins and paints, as it improves the drying speed, hardness, and water resistance of these products. It is also employed in a wide range of other products including radiation-curing monomers, fatty acid rosin and tall oil esters, modified drying oils, polyurethanes and explosives.
It is further used in the manufacture of neopolyol esters which are used in synthetic lubricants, as well as in the preparation of polyvinyl chloride (PVC) stabilizers, plasticizers, antioxidants, adhesives, sealants, varnishes, paints, varnish, lacquers, coatings, synthetic rubber and printing inks. Halogen-free pentaerythritol esters are an environmentally-friendly alternative to conventional electrical transformer fluids as they are readily biodegradable, non-hazardous in water and have excellent resistance to ignition.
Storage and Handling
Mono pentaerythritol should be stored in a cool, dry place away from strong acids, oxidizing agents, acid chlorides and acid anhydrides. It can be expected to remain stable under recommended storage conditions.
The material should be handled in accordance with good industry safety and hygiene practices. Relevant engineering controls including good ventilation should be implemented. Personal protective equipment such as protective gloves, glasses and respiratory protection should be worn. Refer to product SDS for further guidance.
