Naphthenic acid 1. Description 1). clear yellowish to the brown liquid of oil 2). naphthenic acid is the name for an unspecific mixture of several cyclopentyl and cyclohexyl carboxylic acids with molecular weight of 120 to well over 700 au. The main fraction are carboxylic acids with a carbon backbone of 9 to 20 carbons. The naphtha fraction of the crude oil refined is oxidized and yields naphthenic acid. The composition differs with the crude oil composition and the conditions during refined and oxidation. 2. Applications naphthenic acids are used successfully in: 1). Coating driers naphthenic acids metal salts are added to paints and inks to accelerate drying 2). Fuel & lubricants 3). Textile & fabric care 4). Rubber & tire manufacturing 5). Polymers & tire manufacturing 6). Metal working 7). Wood treating 8). Asphalt & concrete 3.

Ultra-dri drier is a kind of environment friendly high efficacy mixed drier, which we develop it through many years producing and experimental practice to meet to the market need. It has no pernicious metal content and is a good substitute of the lead drier. It also has good efficacy for surface dry and complete dry. Compared to the traditional driers, it has some advantages: low consumption, low cost, good membrane, simple process of paint making and easy use.
