摘要： The present invention relates generally to methods for forming peroxyformic acid, comprising contacting formic acid with hydrogen peroxide. The methods for forming peroxyformic acid can include adding formic acid with a relatively lower concentration of hydrogen peroxide, or adding formic acid to a peroxycarboxylic acid composition or forming composition to react with hydrogen peroxide in the compositions. The present invention also relates to peroxyformic acid formed by the above methods. The present invention further relates to the uses of peroxyformic acid for treating a variety of targets, e.g., target water, including target water used in connection with oil- and gas-field operations. The present invention further relates to methods for reducing or removing H2S or iron sulfide in the treated water source, improving clarity of the treated water source, or reducing the total dissolved oxygen or corrosion in the treated water source, using peroxyformic acid, including peroxyformic acid generated in situ.

摘要： Peracid stable fluorescent active compounds in highly acidic, equilibrium peroxycarboxylic acid sanitizing compositions are disclosed as having improved fluorescent stability allowing for monitoring of peroxycarboxylic acid concentration by conductivity and/or optical sensors. Beneficially, the compositions are also low odor and low/no VOC dual functioning acid wash and sanitizing compositions.

摘要： A concentrated liquid sanitizing and rinse composition containing peroxycarboxylic acid(s) and compatible rinse aid surfactants is disclosed. The sanitizing and rinsing compositions are formulated in a single liquid concentrate, replacing a traditional dual product of a sanitizer and rinse aid. The sanitizing and rinsing chemistries are particularly effective at neutral pHs against gram negative organisms at elevated temperatures. Methods of using the concentrated liquid sanitizing and rinse composition are also disclosed.
