方法一:对羟基苯甲酸的生产方法有多种，苯酚钾羧化法较适于工业化生产，该法又分酚钾固相羧化法、酚钾溶媒羧化法、酚钾与二氧化碳的连续气液相法。将40%左右的氢氧化钾溶液与苯酚加入反应锅中混合，于100℃搅拌0.5h，至酚钾液的游离碱为0.3-1.2%。加热，进行常压脱水，至内温为140℃时改为减压脱水，在10.6kPa压力下蒸水约0.5-1h，直至内温达170℃以上。加入溶剂苯酚共沸脱水，至200℃（2.67kPa）结束脱水，得酚钾与酚的复合盐。将制备的上述复合盐继续加热至220-230℃，通入净化无水的二氧化碳，压力维持在0.5MPa，反应2.5h，降温至200℃补加苯酚，保温搅拌30min，然后减压回收苯酚至尽。再通入二氧化碳进行第二次羧化，约需2h。羧化结束后，回收苯酚，冷却至180℃以下，加水溶解，即得羧化液（对羟基苯甲酸二钾盐）。将硫酸逐渐加入羧化液中，于70℃以下中和至pH为6.7。冷却过滤除去硫酸钾，所得粗品滤饼用水重结晶、活性炭脱色，即得含量99%以上的对羟基苯甲酸。对羟基苯甲酸二钾盐也可由水杨酸二钾盐转位得到。因此工业上也可由水杨酸经成盐、转位、中和得到对羟基苯甲酸，但成本较高。另外，生产糖精时的副产物对甲苯磺酰氯，经氨化、氧化、酸析、碱熔、再酸析也可获得该品。该法收率较低，成本较高，而且糖精副产物中往往夹带有毒的杂质邻磺酰胺基甲苯。
用途三:对羟基苯甲酸是用途广泛的有机合成原料，特别是其酯类，包括对羟基苯甲酸甲酯（尼泊金甲）、乙酯（尼泊金乙）、丙酯、丁酯、异丙酯、异丁酯，可做食品添加剂，用于酱油、醋、清凉饮料（汽水除外）、果品调味剂、水果及蔬菜、腌制品等，还广泛用于食品、化妆品、医药的防腐、防霉剂和杀菌剂等方面。对羟基苯甲酸也用作染料、农药的中间体。在农药中用于合成有机磷杀虫剂GYAP、CYP；在染料工业中用于合成热敏染料的显色剂；还可用于彩色胶片及合成油溶性成色剂“538”及尼龙12中用作增塑剂的生产原料。另外，还用于液晶聚合物和塑料。
