Linear alkylbenzene, a colourless oily liquid with specific gravity 0.86g/cm-3, produced by the Kaduna Refinery and Petrochemical Company was sulphonated at -10°C under conditions of freezing mixture of ice/NaCl, using Oleum (65% SO3) in the first process and H2SO4 (98%) in the second process and the results compared. The resultant linear alkylbenzene sulphonic acid was neutralized with varying concentrations of 2M, 4M and 6M NaOH to ascertain the optimal base concentration needed for effective neutralization to different pH values of 7, 9 and 11 to give the active ingredient (AI). Industrial degreaser was formulated by the addition to the AI N,N-bis(2-hydroxyethyl) lauramide, a foam booster/stabilizer prepared from the saponification of coconut oil using diethanolamine, EDTA, corrosion inhibitors and Citronella perfume extracted from the Eucalyptus Citronella plant by steam distillation was added to the formulation to mask the soapy odour to give it more appeal.

Abstract


Linear alkylbenzene, a colourless oily liquid with specific gravity 0.86g/cm-3, produced by the Kaduna Refinery and Petrochemical Company was sulphonated at -10°C under conditions of freezing mixture of ice/NaCl, using Oleum (65% SO3) in the first process and H2SO4 (98%) in the second process and the results compared. The resultant linear alkylbenzene sulphonic acid was neutralized with varying concentrations of 2M, 4M and 6M NaOH to ascertain the optimal base concentration needed for effective neutralization to different pH values of 7, 9 and 11 to give the active ingredient (AI). Industrial degreaser was formulated by the addition to the AI N,N-bis(2-hydroxyethyl) lauramide, a foam booster/stabilizer prepared from the saponification of coconut oil using diethanolamine, EDTA, corrosion inhibitors and Citronella perfume extracted from the Eucalyptus Citronella plant by steam distillation was added to the formulation to mask the soapy odour to give it more appeal.
