The mixture of di-n-propylamine and di-iso-propylamine was then slowly added into the solution as microporous template (SDA).
Sparingly soluble cyclopropenium derivatives with a 2 1 mixture of di-n-pentylamino:diethylamino groups gave poor THF hydrate crystal growth inhibition.
Mass spectrometric analysis of the commercial product revealed a complex mixture of di- or tetra-dansyl-substituted polymyxin B. We synthesized a mono-substituted fluorescent derivative, dansyl[Lys]1polymyxin B3.
Treatment of 1d with excess Co2 CO 8 yielded unexpectedly a mixture of di- and tetranuclear cobalt-carbene complexes 7 and 8, most likely formed through interaction of oxygen.
Sodium triphosphate (Na5P3O10) was synthesized by heating a mixture of di-sodium hydrogen phosphate (Na2HPO4) and sodium di-hydrogen phosphate (NaH2PO4) with a Na2HPO4/NaH2PO4 ratio of 2/1 at 400 °C for 5 h [16].
The best known glyphosate containing herbicides, the Roundup product line, often contain as a surfactant polyethoxylated tallow amine (POEA), a complex mixture of di-ethoxylates of tallow amines characterized by their oxide/tallow amine ratio, that is significantly more toxic than glyphosate [24].
In the ER, the PrP polypeptide undergoes oxidative folding with formation of a single disulphide bond, and the protein is variably modified at two N-glycosylation sites, resulting in a mixture of di-, mono- and unglycosylated forms [6].
Twenty-nine primer sets provided reliable amplification, and 19 of these were selected to have a mixture of di- and tetranucleotide SSRs.
Phthalates that are high-molecular weight, butylbenzyl phthalate (BBzP), di-2-ethylhexyl phthalate (DEHP) and mixtures of di-n-octyl phthalates (DnOP), are most well-known for their use as plasticizers in polyvinyl chloride (PVC) materials such as food packaging, flooring, and medical devices [ 2, 3].
However, when an equimolar mixture of mono-, di- and tetra-ubiquitin of K63 linkage was used, di- and particularly mono-ubiquitin were strongly preferred over the tetramer.
A mixture of mono-, di-, and trialkylated amines, and sometimes also the quaternary ammonium salt, often results: RCH2X + NH3→ RCH2 2NH (RCH2 3NH, (RCH2 4N+X−RCH2)4Not− Not all alkyl halides are effective reagents; the reaction is sluggish with secondary alkyl groups and fails with tertiary ones.
