Die Cooligomerisierung von butadien mit α-hydroxycarbonsäureestern

1977

Abstract Glycolic acid butyl ester as well as lactic acid ethyl ester react with butadiene in the presence of palladium(II) acetylacetonate and triphenylphosphine as catalyst. The main product is the 2-trans, 7-octadienyl ether of the hydroxy acid ester, which is formed in yields from 65 to 80% at room temperature.

Raman spectroscopy of glycolic acid complexes with N2

2019

High overtone excitation induced conformational isomerization of glycolic acid – nitrogen complex in an argon matrix was investigated by Raman spectroscopy. The interaction between glycolic acid and nitrogen change the green light (532 nm) induced isomerization processes compared to non-complexed glycolic acid. The 180° rotation around of the Csingle bondC bond and stabilization of carboxyl Odouble bondCsingle bondOsingle bondH dihedral angle to trans position were the main conformational changes observed in the complex of the lowest energy conformer and nitrogen. Interestingly, only one stable light-induced conformational product was observed, which isomerises back to the lowest energy con…

FTIR matrix isolation and theoretical studies of glycolic acid dimers

2018

Glycolic acid (GA) dimers were studied in low temperature argon matrices by means of FTIR spectroscopy. Experimentally, the dimers were produced when monomeric glycolic acid molecules were thermally mobilized upon annealing of argon matrices at 25–35 K. The experimental spectra observed upon annealing indicate the presence of three different dimer structures. Computationally, MP2 and DFT calculations were used to study the potential dimer species in order to scrutinize the possible dimer structures, their energetics and their spectral features. Altogether 27 local minima were found for dimer structures for the three lowest conformers of glycolic acid considered based on previous studies on …

Biotechnological innovations in fermentation process of brewing and honey-based beverages industry

2022

La ricerca di microrganismi fermentanti in grado di migliorare le proprietà microbiologiche, fisiche, chimiche, sensoriali e organolettiche delle bevande alcoliche fermentate come vino, birra, idromele, sidro, è considerata ad oggi un punto chiave per lo sviluppo del settore. Negli ultimi anni, l'aumento della domanda al consumo di nuove bevande fermentate ha causato un enorme bisogno di tecnologie di produzione innovative al fine di ottenere diverse tipologie di prodotti caratterizzati da proprietà sensoriali peculiari. Per raggiungere tale obiettivo, l’impiego di nuovi microrganismi, sia fermentanti che non fermentanti, in grado di conferire al prodotto caratteristiche organolettiche pecu…

Feasibility and Safety of Laparoscopic Complete Mesocolic Excision (CME) for Right-sided Colon Cancer

2020

OBJECTIVE The aim of this prospective clinical study is to compare short-term outcome of laparoscopic right hemicolectomy using the Complete Mesocolic Excision (CME group) with patients who underwent conventional right-sided colonic resection (NCME group). SUMMARY BACKGROUND DATA Although CME with central vascular ligation in laparoscopic right hemicolectomy is associated with a significant decrease in local recurrence rates and improvements in cancer-related 5-year survival, there may be additional risks associated with this technique because of increased surgical complications. As a result, there is controversy surrounding its use. METHODS In this randomized controlled trial, several prim…

The use of combination therapy with 20% glycolic acid and fractional mesotherapy to reduce acne scars: a case repor

2019

Background: Acne scars are a common problem for those suffering from acne vulgaris. They may result in low self-esteem, especially if located in visible places such as the face. They may even impede normal societal functioning and withdrawal from the environment. Aim of the study: To investigate the effects of 20% glycol acid and fractional mesotherapy on the reduction of acne scars. Material and methods: We used interviews, case analysis and assessment of the effects of glycolic acid treatment and fractional mesotherapy on a 33-year-old female patient who experienced severe phlegmonosa acne. Case report: This 33-year-old female patient was struggling with acne at age 29. Purulent cysts wer…
