Uses

Used in Industrial Water Systems:
PH 800/20 is used as a pH control agent for maintaining the optimal pH level in industrial water systems, ensuring the prevention of corrosion and scale buildup.
Used in Boiler Systems:
In the context of boiler systems, PH 800/20 is used as a corrosion inhibitor to protect metal surfaces from degradation, thereby extending the equipment's lifespan and ensuring efficient operation.
Used in Cooling Towers:
PH 800/20 is utilized as a dispersant in cooling towers to prevent scale buildup and sedimentation, which can hinder heat transfer and lead to system inefficiencies.
Used in Wastewater Treatment Systems:
Within wastewater treatment systems, PH 800/20 is employed to manage the pH level, which is critical for the biological processes involved in wastewater treatment, as well as to control the corrosiveness of the wastewater to the treatment infrastructure.

Molecular rods based on oligo-spiro-thioketals

We report on an extension of the previously established concept of oligospiroketal (OSK) rods by replacing a part or all ketal moieties by thioketals leading to oligospirothioketal (OSTK) rods. In this way, some crucial problems arising from the reversible formation of ketals are circumvented. Furthermore, the stability of the rods toward hydrolysis is considerably improved. To successfully implement this concept, we first developed a number of new oligothiol building blocks and improved the synthetic accessibility of known oligothiols, respectively. Another advantage of thioacetals is that terephthalaldehyde (TAA) sleeves, which are too flexible in the case of acetals can be used in OSTK rods. The viability of the OSTK approach was demonstrated by the successful preparation of some OSTK rods with a length of some nanometers.

Synthesis and Thermal Stability of 4-Substituted 1,2-Dithiolanes

Disodium 2-cyano-3,3-bis(sulfido)propenamide (6) has been used as a double synthon for SH- in the preparation of 1,3-dithiols.Oxidation of the dithiols gives 4-substituted 1,2-dithiolanes, e.g. asparagusic acid (3).The energy splits between the first and second ionization potantials in 3 and the other 1,2-dithiolanes (8-11) have been determined by ultraviolet photoelectron spectroscopy.The relative stability of these compounds do not correlate with the measured ΔE values.Hence, factors besides the S-S torsional angle must influence these stabilities.

SYNTHESIS OF NEW MACROCYCLIC POLYTHIAETHER

Synthesis of a new macrocyclic polythiaether (12) which is easily obtained in a good yield via 2,6-dithia-4-spiroheptane (6) is described.Several reactions of pentaerythrityl bromide (1) with nucleophiles and a few ring opening reactions of 6 with methyl iodide are also described.
