Conversion of Alcohols to Acetates
AOS Products Private Limited provides services/ consultancy for manufacturing process and techniques to convert alcohols to acetates. For example:
Steam Distillation Unit
- Linalool to Linalyl Acetate
- Geraniol to Geranyl Acetate
- Cis-3 Hexanol to Hexanyl Acetate, etc and many more.
Unit is designed to handle a number of aroma bearing plants , flowers , roots , herbs and other products at different process conditions for carrying out studies & standardization of process condition.
- Charge capacity - 200 Kgs. Herc/ Planting material)
- Capacity of the unit is:
- Gross Volume 750 Litres
- Herb Volume 250 Kgs.
Value addition in essential oils for increasing share of margin, a multiferial reactor capable of handling diverse chemical reactions is also a part of pilot plant.
- Reactor Capacity - 300 Litres
- Charge Capacity - 200 Kgs.
The reaction assembly coupled with fractional distillation column can as well be used for manufacture of drug intermediates also, while it is idle for aroma chemical manufacture.Hydrogenation Unit
A Hydrogenation unit for value addition in essential oil & aroma chemicals by reduction process has recently been added to pilot plant facility. This unit has been designed to operate at 120 Psig. Pressure & 150 c temperature with jacket & spiral stiffeners facility.
Vessel Capacity - 250 Litres
Charge Capacity - 180 KgsSolvent Extraction Unit
Solvent extraction unit can handle manufacture of concretes, resinoids, oleoresins and absolute from flowers , resins , gums & spices. For solvent recovery in traces , this unit is attached with stripping / Solvent Recovery unit with appropriate heating & vacuum arrangements.
- Extractor Capacity - 700 Litres
- Change Capacity - 150-200 Kgs.
The versatile design of solvent extraction unit is quite suitable for herbal extraction from soft plant material e.g. leaves, twigs flowers, soft bark etc. by circulating decoction process. The unit capacity being used for solvent extraction by:
Fractional Distillation Units
- Percolation at ambient temperature
- Hot solvent extraction by the soxhlet method
- Repeated leaching with hot or cold solvent
- Extraction by hot /cold solvent under agitation
A fractional distillation unit with arrangements to operate it at reduced pressure & indirect heating system for processing of essential oils into isolates and aroma chemicals to a high degree of purity with acceptability to perfumers/flavourist is the attraction of this unit. This fractional distillation column is equipped with pneumatically controlled reflux divider with automatic timer and temperature sensors at all segments of the column for efficient operation and better separation of the isolates.
- Recoiled Capacity - 250 Litres
- Charge Capacity - 180 Kgs
In addition to semi-commercial capacity fractionating column as above, various capacity of glass fractionating columns are also available for process conditions development and standardization
Menthol Oil Crystallization Units
Menthol processing unit for menthol flakes & bold crystals with arrangement to separate the mother liquor from the product is also a part of pilot plant.
- Freezers Capacity - 1000 Litres
- Charge Capacity - 700 Kgs.
- Glass Lined Reactor Attached with Cryostate
- Charge capacity:- 60 Kgs.

NEW AREAS AND SYNERGY
We always believe in working closely with industry to come out with innovative methods/techniques of processing. Following are the areas we have identified and have done some initial work. We would like to associate and work jointly with organizations to share the benefits mutually on prearranged basisRapid chilling of CMO using direct contact injection chilling.
Fractional crystallization of L-Menthol crystals: Sound technical basis still lacks in this area.
Recovering high value low volume products out of pitch discarded after CMO distillations.OTHER TECHNOLOGY:
Isomers Separation: More than 25 plants engineered are working satisfactorily, Cutting across several domains
Alcohol Distillation to RS, ENA, Absolute alcohol by extractive or Azeotropic Distillation.
Alcohol based chemicals: Acetaldehyde, Acetic acid, Ethyl acetate, Ethylene.
Oil & Gas/Petrochemicals: Separations involving c3 to c8.
Aroma and fine chemicals: Equipped to handle typical requirements of high value products
Essential oils extraction and their further fractionation.
Biotechnology: Aerobic Fermentors , Fermentation auxiliaries like Sterilization and CIP systems.
