Mono-/?-hydroxyethylation

Polyurethanes. Metal-containing polyurethanes have been synthesized by poly-condensing Co2+, Cu2+ salts of mono(hydroxyethyl) phthalate with hexa-methylene diisocyanate and tolylene diisocyanates [47] (Fig. 19).

Results obtained for two mixed plastics are summarized in Table 4. A balance exists between process temperature, plastics feed rate, and product yields (67). For example, lower temperatures increase wax formation due to incomplete depolymerization. Slower feed rates and increased residence times reduce wax formation and increase the yield of Hquids. The data summarized in Table 4 illustrate that the addition of PET to a HDPE PP PS mixture changes the performance of the Conrad process. Compared to the reference HDPE PP PS mixture, increased amounts of soHds ate formed. These are 95% terephthahc acid and 5% mono- and bis-hydroxyethyl esters. At higher temperatures, apparentiy enough water remains to promote decarboxylation. 

Commercial Disperse Azo Dyes. The first proposal to use insoluble dyes in suspension in an aqueous foam bath, ie, disperse dyes, to dye cellulose acetate was in 1921 (60). Commercialization of disperse dyes began in 1924 with the introduction of the Duranol dyes by British Dyestuffs Corporation (61) and the SRA dyes by British Celanese Company (62). In contrast to the acid monoazo dyes, derivatives of benzene rather than of naphthalene are of the greatest importance as coupling components. Among these components mono- and dialkylariifines (especially A/-P-hydroxyethyl-and A/-(3-acetoxyethylanifine derivatives) are widely used couplers. Nitrodiazobenzenes are widely used as diazo components. A typical example is CeUiton Scarlet B [2872-52-8] (91) (Cl Disperse Red 1 Cl 11110). 

All lene Oxides and Aziridines. Alkyleneamines react readily with epoxides, such as ethylene oxide [75-21-8] (EO) or propylene oxide [75-56-9] (PO), to form mixtures of hydroxyalkyl derivatives. Product distribution is controlled by the amine to epoxide mole ratio. If EDA, which has four reactive amine hydrogens, reacts at an EDA to EO mole ratio which is greater than 1 4, a mixture of mono-, di-, tri,-, and tetrahydroxyethyl derivatives of EDA are formed. A 10 1 EDA EO feed mole ratio gives predominandy 2-hydroxyethylethylenediamine [111-41-1], the remainder is a mixture of bis-(2-hydroxyethyl)ethylenediamines (7). If the reactive NH to epoxide feed mole ratio is less than one and, additionally, a strong basic catalyst is used, then oxyalkyl derivatives, like those shown for EDA and excess PO result (8,9).

Using nitric acid-acetic acid, 9-(2-hydroxyethyl)-, 9-(2-chloroethyl), and 9-n-butylcarbazoles have been mono-3-nitrated, whereas 9-carboxy-methylcarbazole gave a good yield of the 3,6-dinitro derivative.

Rieche and Meister34 obtained bis(l-hydroxyethyl) peroxide (21) from 2 moles of acetaldehyde and 1 mole of hydrogen peroxide. Treatment of 21 with phosphorus pentoxide in ether followed by distillation gives 3,5-dimethyl-l,2,4-trioxolan (2,3-butylene ozonide) (22) as the distillate and dimeric butylene ozonide with a ten-membered ring structure (23) as the residue.23-34 Thermal decomposition of (23) at 60 to 80° in vacua yields polymeric ethylidene peroxide (25), 3,5,7-trimethyl-l,2,4,6-tetroxepan (mono-...
