摘　　要：以苯为初始原料，采用先硝化后磺化及用液体三氧化硫作磺化剂新工艺生产间硝基苯磺酸钠，降低了原材料和动力的消耗，提高了产品的纯度，减少８５．７％的废渣排放量，并使生产装置的原生产能力增大两倍以上，获得了显著的经济效益。Benzene is used as original material,nitrated first,then sulfonated by liquid sulphur trioxide. The new technolohy of producing sodium m-nitrobenzenesulfonate cuts down the consumption of raw materials and energy remarkably.The emission of the waste residue goes down by 85.7%. The product purity is improved. The production capacity of original facilities has increased more than twice.The obvious economic benefit is obtained.
