Withdrawal symptoms in a neonate whose mother had been a chronic user of propoxyphene hydrochloride have not, as far as we are aware, been reported. We observed withdrawal symptoms in a neonate at 20 hours of age; the mother had taken propoxyphene hydrochloride regularly for over 3 years prior t...

A total of 342 patients with postoperative or fracture pain were divided into 7 groups and were treated with one of the following: 32, 65, or 130 mg of propoxyphene hydrochloride; 50, 100, or 200 mg of propoxyphene napsylate; or placebo. Each of the treatment groups experienced significantly mor...

Described is the case of a patient who developed left bundle branch block following acute propoxyphene hydrochloride overdosage. The left bundle branch block was transient and associated with no permanent sequelae. Previously documented cardiac abnormalities, specific narcotic antagonist therapy...

Publisher SummaryThis chapter discusses the physical properties and synthesis of propoxyphene hydrochloride. Propoxyphene hydrochloride is a white, crystalline powder with no noticeable odor and a bitter taste. The melting range is 162.5–168.5°C. The specific rotation for a one percent solutio...

A rapid, simple and stereospecific procedure for the simultaneous assay and determination of the enantiomeric purity of pharmaceutical-grade propoxyphene hydrochloride is described. The procedure is faster, less hazardous and more accurate than the U.S.P. XXI method, but unlike that method it is...

In the course of our studies on Cerpegin analogues synthesis, a serendipitous reactivity of enaminolactone nitrile has been observed. Instead of expecting iminocerpegins, we have gained new class of substituted 2-aminopyridines. The methodology has been applied on a wide range of primary amines,...

The voltammetry of self-assembled monolayers (SAMs) of 7-ferrocenycarbonyloxy-1-heptanethiol (FcCO2(CH2)7SH) has been studied as a function of temperature. Such SAMs are, when oxidised, susceptible to loss of ferrocene via nucleophilic attack, but at temperatures only just above room temperature...

Raman spectra of 2,4,4-trimethyl-2-pentanethiol were measured. The spectral analysis with the normal coordinate treatment indicated that this molecule takes the gauche conformation about the CCCS bond in the solid state and the trans and gauche conformations in the liquid state. The Raman band...

Keeping of O,O’-bis(2-benzylideneaminophenyl) phenylphosphonite in a CCl4 solution for 50 days resulted in its spontaneous rearrangement into 1,6,7-triphenyl-3,4:9,10-dibenzo-2,11-dioxa-5,8-diaza-1-phosphatricyclo[6.3.0.01,5]undeca-3,9-diene, a representative of spirophosphoranes with P–N bonds.

The reaction of 1,2-diaza-1,3-butadienes with dialkyl phenylphosphonites under solvent-free conditions proceeds via zwitterionic intermediate and gives, by precipitation, the stable ylidic α-phosphanylidene-hydrazones that, in turn, can be transformed into the corresponding 3-phenyl-2H-1,2,3λ5...

The mechanism of photochemical isomerization of 3-phenylpropene to 1-phenylpropene in the presence of hydridotetrakis(diethyl phenylphosphonite)cobalt(I) (HCoP4; P = P(OEt)2Ph) has been claimed to be a ‘photoassisted reaction’, on the basis of the fact that the isomerization stopped immediatel...

Acid chlorides, complexed with excess aluminium chloride, reacted with ethene to form 3-methyl-2-buten-1-ones, i.e. rearranged di-addition products having a terminal isoprenoid skeleton, together with the usual β-chloropropanones. The latter were the sole products in the absence of excess catal...

Hydrogenation of 4-tert-butylphenol (4-TBP) hydrogenation in isopropanol at 433 K and 1–2 MPa of hydrogen pressure was performed in an upflow three-phase reactor. Overall conversion was ca. 90–97% with 4-tert-butylcyclohexanol as the predominant product. The cis/trans ratio in 4-tert-butylcycl...

In this present work, combing density functional theory (DFT) and time-dependent DFT (TDDFT) methods, we investigate a novel white light material 2,2′-(thiazolo[5,4-d]thiazole-2,5-diyl)bis(4-tert-butylphenol) (t-HTTH) about its dual intramolecular hydrogen bonding behaviors and relative excited...

Lab-scale vertical flow constructed wetlands (CWs) were used to remove phenol, bisphenol A (BPA), and 4-tert-butylphenol (4-t-BP) from synthetic young and old leachate. Removal percentages of phenolic compounds from the CWs were in the following order: phenol (88–100%) > 4-t-BP (18–100%) ≥ BP...

Gas-phase hydrogenation of 4-tert-butylphenol (4-TBP) over 1% Pt/SiO2 to cis and trans 4-tert-butylcyclohexanol (4-TBCHOL), via the intermediate 4-tert-butylcyclohexanone, was studied in a differential reactor at atmospheric pressure and at temperatures between 127 and 227 °C. The formation of ...

Influence of UV and combined MW–UV irradiation on 4-tert-butylphenol (4TBP) transformation was investigated in the presence and in the absence of sensitizers with different value of singlet and triplet energy and in the presence of solvents with different polarity. Irradiation by UV and also by...

A facile solvothermal route is successfully developed to synthesize Bi4O5I2, a novel I-poor bismuth oxyiodide, with hierarchical nanoflake structure. The composition, structure, morphology, formation mechanism, photoabsorption, energy band, and photocatalytic properties of this material are syst...

4-tert-butylphenol (4-t-BP), an endocrine disrupting chemical, is widely distributed in natural bodies of water but is difficult to biodegrade. In this study, we focused on the transformation of 4-t-BP in photo-initiated degradation processes. The steady-state photolysis and laser flash photolys...

In this study, the activation of persulfate induced by Fe(III) species, including 5 kinds of iron oxhydroxides (IOs) and dissolved Fe3+ under dark condition were investigated. Ferrihydrite (FH) and akaganeite (AK) showed the highest activity in 4-tert-butylphenol (4tBP) removal. The 4tBP degrada...
