CARDANOL OIL
Tradeasia International Pte. Ltd is a privately owned, independent company headquartered in Singapore. Tradeasia International was first established in 2004 with the sole intention of carrying out chemical distribution services especially to commodity industries in many parts of the world.
Cardanol Oil
Cardanol is a phenolic lipid obtained from anacardic acid, the main component of cashew nutshell liquid (CNSL), a byproduct of cashew nut processing. Cardanol finds use in the chemical industry in resins, coatings, frictional materials, and surfactants used as pigment dispersants for water-based inks. It is used to make phenalkamines, which are used as curing agents for the durable epoxy coatings used on concrete floors.[1] The name of the substance is derived by contraction from the genus Anacardium, which includes the cashew tree, Anacardium occidentale. The name of the genus itself is based on the Greek word for heart.[2]
Manufacturing Cardanol
Cardnol is distilled from Cashew Nut Shell Liquid. A batch of Decarboxylated CNSL is heated to 280degree celcius under Vaccum in a reactor. After few minutes of heating the vapours of Cardanol come into the condenser where it is cooled using suitable coolant to convert the vapour into liquid. The liquid is collected into a reciever. The process runs for a fixed time after which the receivers and reactors are emptied and fresh batch is started. The Cardanol is filled in tanks or barrels and Residol in barrels after few minutes of cooling.
Samples are drawn for preliminary testing of Colour, Viscosity and pH. Cashew nut shell liquid from different sources is purchased and stored separately for distillation. Cashew nut shell liquid is measured using a batch tank and taken into reactor where it is distilled under vacuum at 280 degree celcius.
After the stipulated batch time , Cardanol (Grade 2) is drained from the receiver and stored in vacuum tanks or packed in drums as required . Residol is drained from the reactor into a cooling tank and stored in MS drums .
Application To Use Cardanol
Cardanol For Production
Cardanol finds use in the chemical industry in Oil and Alcohol soluble resins, laminating resins, rubber compounding and coatings, serving as an excellent raw material for the preparation of high grade insulating varnishes, paints, enamels. It is used in friction materials, and surfactants as pigment dispersants for water-based inks and to make phenalkamines, which are used as curing agents for the durable epoxy coatings used on concrete floors. Cardanol can substitute Phenol in up to 30% in phenolic resins used as plywood bonding resin and for the lamination industries.
