- alpla-Campholenic aldehyde (CA) is an enormously important and industrially relevant perfumery compound. CA is used as the primary precursor of sandalwood oil.
- CA is largely used by aroma industries for the production of Sandalwood oil as the end product to be used in various cosmetic/perfumery items. Due to huge demand, CA is primarily imported from China and a few European countries.
- In general, the existing processes for this chemical employ environmentally questionable reagents and additives leading to production of (over) stoichiometric industrial wastes with an increase in the environmental hazards.
- CSIR-CSMCRI has developed an indigenous process for CA in a sustainable manner by using locally available raw materials and reagents.
- The CSMCRI process comprises of a two-step synthetic route starting from inexpensive alpha-pinene
- Environmentally less hazardous process that employs indigenous raw materials
- A clean process giving aqueous wastes
- Scaled up to 1 kg level
- High yield (>85%) and purity (93-95%) for CA were achieved
- The process is consistently reproducible and thus, reliable for industrial scale production
Demonstration is ready at 1 Kg scale per batch with respect to Campholenic aldehyde
The total import of CA by Indian industries is significantly large (total import = 1976.6 MT, during 01.01.2018 to 31.07.2023). Owing to the cost-competitiveness and environmentally benign nature, the commercialization of the process is expected to result in import substitution of CA.
The CSMCRI process is safe, clean and environment friendly for the sake of betterment of life. All raw materials are non-toxic, non-hazardous and non-corrosive in nature. Water produced in the process can be treated at ETP before disposal.
Alpha-Pinene, Hydrogen Peroxide, Catalyst and Solvents
Customized reaction vessel equipped with addition pumps, Storage tanks, Solution preparation tanks, Jacketed Reactor with stirrer, Pumps, Filtration unit, Distillation unit.
The process is simple and utilize low cost starting materials without using complicated plant design. Therefore, ideally suitable for start-ups and MSME sectors. The process could be techno-economically feasible and competitive in the open market.
