Thermal Susceptibility of Nickel in the Manufacture of Softeners

The chemical industry includes a wide range of factories focused on obtaining final products as: (i) plastics; (ii) fibers; (iii) rubber; (iv) perfumery and cosmetic products; (v) cleaning products. Although the level safety in activities installations this sector is very high, use dangerous substances implies an increased risk suffering accident involving emission hazardous substances, as well endangering workers. In case manufacture softeners, presence isopropanol (C3H8O), dimethyl sulfate (CH3)2SO4), have been reported to be cause most cases. European database (eMars) which impurities nickel (Ni) hydrogenated tallow used raw material for softener production may thermal reactivity chances spontaneous combustion. This paper analyzes results obtained with Maciejasz Index (MI) understand susceptibility these liquid state. show that combinations (hydrogenated catalyst) other (isopropanol, sulfate, sulfuric acid) are not sufficiently reactive oxygen
