Vineeth Chemicals is a proprietary company set up by a young and enterprising chemical engineer, Mr.Vishwanath P.Shetty, M.E.(Chem.), in the year 1986. The Company is engaged in the manufacturing of Hydrogenation Catalysts and allied products viz. Raney Nickel Catalyst (Active), Raney Cobalt Catalyst, Precious Metal Catalysts viz.Palladium/ Platinum supported on inert materials such as Activated Charcoal, Calcium Carbonate, Alumina, Barium Sulphate, Kieselguhr etc. The company is also engaged in manufacturing Nickel-Aluminium Alloy Powder (50:50 & 30:70) and Devardas Alloy. Company is also manufacturing Lindlar Catalyst which is used for selective hydrogenation of triple bond to double bond.. Raney Nickel Catalyst (Active) is company's key product and its market share is around 60%.

Company's installed capacity for Raney Nickel Catalyst (Active) is around 150 tones per annum and that of around 2400 kgs. for precious metal catalysts. Company also undertakes reactivation of Spent Raney Nickel Catalysts and recovery of precious metals from spent containing precious metal catalysts which helps the customers in a big way to bring down their cost of operation.

Company is highly quality conscious. The company has got its own R & D Center where product development and improvement is an on going activity. The R & D Center is being looked after by highly experienced technical staff. Company has got documented procedures and systems. Quality of company's products on several occasions has been proved to be superior to imported products. Company's products are accepted by large number of companies including multinational pharmaceutical companies.

Company's products other than Nickel Oxide are used mainly in the manufacture of bulk drugs, drug intermediates, aromatic chemicals, specialty chemicals, rubber additives, pesticides, dyes and dye-intermediates, fine chemicals and organic chemicals etc. where hydrogenation is the key reaction. Nickel Oxide, however, is used for imparting green shades in glass manufacture.

Company markets its products at most competitive rates. Material Safety Data Sheets are provided to customers for storage and handling. The company provides after sales service and also technical consultation to its customers.

Company is highly conscious about prevention of environmental pollution and has adopted mechanism to ensure environmental protection. Ever since its inception the company has maintained excellent industrial relations with its employees. All the employees of the company are treated like family members. The employees are periodically educated about house-keeping and safety aspects pertaining to manufacturing, storage and handling as most of the products are pyrophoric in nature.
