PBTC corrosion inhibitor, PBTC antiscalant
CAS No. 37971-36-1
Molecular Components: C7H11O9P
Molecular Mass: 270.13
PBTC corrosion inhibitor is very useful just as both equal antiscalants as well as corrosion inhibitors. due to the truth of its structural function of carboxylic acid and phosphoric acid. The PBTC antiscalant is steady and good performance within the situation of high hardness, temp, pH value, and then listed matter concentration.
While ordinarily establishing with many other organophosphates, PBTC acid as well broadly works jointly with zinc salts which solubility it’s going to rise. PBTC antiscalant is able to raise zinc sodium solubility. PBTC also provide a bigger tolerance to oxidation chemicals such as chlorine or bromine in the system.
The original reaction of PBTC corrosion inhibitor production is normally between dialkyl phosphite (generally dimethyl phosphate in China) and also maleic acid dimethyl ester using a common catalyst. Tetraalkyl ester of phosphonosuccinic acid forms along with quickly responded together with methyl acrylate. The next thereupon saponification outputs PBTCA.

As being a good inhibitor to both the scale and corrosion, PBTC corrosion inhibitor is definitely the great stabilizer for zinc sodium. It can be commonly applied to the re-filling system and circulated cooling system for oil areas, metal mills, and also mines. PBTC antiscalant can be utilized within conditions of, high hardness, high alkali, and high concentration index. In addition, PBTC is used in order to chelate steel ions in lavation and also detergent fields as steel detergent. In pH 7-10, 5-15 mg/L is usually recommended if only PBTC acid.
PBTC corrosion inhibitor is normally applied along with the zinc sodium, copolymer, organophosphine, imidazole, and also other water treatment chemicals. While used by itself, the actual dosage of 5-15 mg/l is normally recommended.
Package and Storage:
200L plastic drum,IBC(1000L),customers’ needs. Storage for just one year within shady space and dry space.
PBTC acid is one of the fine chemical products. To ensure its performance, moisture should be avoided. Because some water treatment agents react quickly if they encounter moisture. So be sure to store PBTC antiscalant in a dry area. This is the most basic requirement.
Second, different water treatment agents are placed in different places. Also, some of the water treatment agents put together to produce a chemical reaction. And it is easy to make mistakes and cause a lot of trouble.
Since the storage of PBTC corrosion inhibitor should be kept dry, keep it away from water sources. The last point is that since the drug contains organic substances, keep away from open flames and avoid reactions.
Safety Proper protection:
Acidity, Avoid contact with eyes and skin area, once contacted, flush with water.
