Usage

Description

BUTTPARK 32\09-93 is a specialized chemical mixture developed for the petroleum industry, specifically as a drilling fluid additive. This proprietary blend consists of butyl acetate, alkylaryl sulfonate, and other undisclosed components, which are meticulously formulated to enhance the lubricity and thermal stability of drilling mud. The inclusion of butyl acetate serves to diminish friction and heat during drilling, while the alkylaryl sulfonate functions as a surfactant and dispersant, facilitating the suspension of solid particles and preventing their aggregation. Collectively, these properties aim to optimize the performance of drilling fluids, thereby increasing the efficiency and effectiveness of oil and gas extraction processes.

Uses

Used in the Petroleum Industry:
BUTTPARK 32\09-93 is used as a drilling fluid additive for the purpose of improving the lubricity and thermal stability of drilling mud. The butyl acetate component is utilized to reduce friction and heat generation during the drilling process, ensuring smoother operations and equipment longevity.
Furthermore, BUTTPARK 32\09-93 is used as a surfactant and dispersant in the petroleum industry. The alkylaryl sulfonate in the mixture aids in the suspension of solid particles within the drilling mud, preventing their settling and maintaining a consistent fluid composition. This contributes to the overall efficiency of oil and gas extraction operations by reducing the need for frequent fluid adjustments and minimizing the risk of equipment damage due to particle buildup.

Regioselective Synthesis of o-Benzenediboronic Acids via Ir-Catalyzed o-C-H Borylation Directed by a Pyrazolylaniline-Modified Boronyl Group

Ir-catalyzed ortho-directed C-H borylation of pyrazolylaniline (PZA)-modified arylboronic acids with bis(pinacolate)diboron afforded o-benzenediboronic acids in which two boronyl groups are differentially modified by pinacol (PIN) and PZA. By using this borylation after nondirected Ir-catalyzed C-H borylation, o-benzenediboronic acids are conveniently synthesized from unfunctionalized arenes. The differentially modified o-benzenediboronic acids undergo selective oxidation and Suzuki-Miyaura cross-coupling at the PZA-modified boronyl groups, affording o-functionalized arylboronic acids selectively.

A simple synthesis of 5-(2-Aminophenyl)-1H-pyrazoles

A four-step synthesis of 1-substituted 5-(2-aminophenyl)-1H-pyrazoles 5 as a novel type of histamine analogs and versatile building blocks for further transformations was developed. The synthesis starts from commercially available 2-nitroacetophenone (12), which is converted into the enamino ketone 13 as the key intermediate. Cyclization of the key intermediate 13 with monosubstituted hydrazines 14a-14l afforded the 5-(2-nitrophenyl)-1H-pyrazoles 17a-17l. Finally, catalytic hydrogenation of the nitro compounds 17a, 17c-17e, and 17g-17j furnished the title compounds 5a, 5c-5e, and 5g-5j, respectively, in good yields. As demonstrated by some further transformations, additional functionalization of compounds 17 and 5 is feasible, either by electrophilic substitution at C(4) of the pyrazole ring, or at the NH2 group.
