Naphthalene Robust in 1989 

As Phthalic Outlet Performs 

The caphtbaleoe Industry L» robust In 

1989. Major derivative phthalic anhydride is performing well, and sales volumes to both emerging and mature 

smaller market segments are meeting 

positive- expectations. 

Steady growth in demand for purified 

naphthalene has prompted Allied-Signal Inc. 

to plan a -O.OOv-mctric-lon facility at Its 

Ironton, Ohio tar distillation plant (CMR, 3/ 

IS/89, pf. 4). 

Petroristics Inc.. a consulting firm In Irvington. N.Y., la releasing a report, "US Naphthalene Market Opportunities" projtctlng a 

marked rite In naphthalene consumption by 

the phtiialic anhydride industry In tbe 1990's. 

Since the early 1980s, all US phthalic anhydride producers except Hopper Industries, 

which supplies itself with naphthalene, have 

devoted their feedstock arrangemerrts exclusively to orthoxylene. 

But Li the late 1980's. orthoxylene costs 

have increased substantially and are widely 

expected to remain at hiLgb levels lotg-tenn. 

while m pc'J-elene costs have been fairly stable at a significantly lower level. 

DUAL FEED CAPABnjTY 

Industry sources indicate that several, if 

not most US phthalic jnhydride makers are 

beginnrig to seriously evaluate the necessary steps for successfully achieving dual 

naphtb-Jene/orthc-ylene feedstock capability in the coming decade. 

A phthalic anhydride manufacturer in 

Italy svritched over a few years age to dual 

feed, and this has contributed to bet-tby US 

naphthalene export sales. 

Sources say that such a move requires tbe 

installation of a ner catalyst, and that the 

naphthalene used Deeds to be mod-fitd, possibly by in evaporator. The dual feed system Is 

said to be highly flexible in terms of napfathaleoe/orthoxyle_e percentage mix, as tbe 

two arc blended together prior to being fed 

into a F reduction unit 

Indartiy sources note that a major question mark for interested partlei in the 

phthalic anhydride industry is the availability of Uurge enough supplies of naphthalene to 

meet tlie potential rise in demand. 

A major point of the Petrogistics study, 

says a naphthalene producer, "appears to h.* 

drumning up interest among petroleum 

companies logo out and recover naphthalene 

potentially available in their streams low 

that is not being recovered." 

Petrogistics says It envisions pHroleu-i 

naphthalene production from steam crack .T 

pyrolysis is gas oil and refinery fluid nalytic cracker ligtt cycle oil becoming the 

bac-t»?oe of future US naphthalene supply. 

Fm-jberrnore, Petrogistics says tiiat "foreseeable domestic naphthalene chemical demand and overseas export operations could 

be supplied from underutillxed/ldled US 

toluene bydrodralkylatlon units converted to 

naphthalene operation." 

The rupbtbalene maker benefitting perhaps the roost from the present situation is 

Koppers. which Is enjoying a substantial 

competitive edge against Its phthalic anhydride competitors, most of whom are not 

bark-integrated to orthoxylene.

pMhalic lKJastry. a atxeeN* portion b s c 

counted for by the Insecticide earbaryL produced In the US by Rhooe-Poulerc A naphthalene supplier says that the generally mature market for carbaryl and related product! appears to be needed for a relatively 

strong year. 

Saperplastici-ers, a form of naphthalene 

sulfocate-formaldefayde condensates taxed la 

concrete additive-, are de-nonstratlag the

tobe satisfactory.

ISOPROPYL ALCOHOL - List and offlist pricing for Isopropyl slcobol moved up by 

2c. per gallon on April 1 at most producers. 

Source* My this Increase still does not make 

up for increased propylene costs. European 

material has been high-priced, not an alternative source, because propylene Is lighter 

and more expensive there. Producer! expect 

the IP A Increase to be accepted because alternative coatings solvents, such u ethanol, 

are still making np margins squeezed by 

ethylene costs.

S1YRJENE — Producers My they are endeavoring to maintain price stability on domestic sales despite the recent weakness In 

overseas markets. 

"Styrene pricing here will come down 

eventually." coocedes a manufacturer, "hot I 

don't think it will drop as soon u by as much

A representative large volume contract 

posting of 49c. per pound Is reported, higher 

than an export quotation of 46c per pound 

For all ot 1938, export pricing ran well above 

domestic levels. 

While producers My that several maintenance outages scheduled In the coming 

months should serve to forestall an oversupply situation In the US, a weakening In oversea:) markets could ultimately back product 

up here as the Incentive to ship declines.

Superconducter 

Demonstrated 

By Bellcore R&D 

Research?!* from Bellcore. Rutgers 

University and Japan's Nippon Electric 

Company list week reported depositing 

superconducting thin films on silicon 

and registering critical current densities 

300 times higher than those of previous 

attempts. 

Tbe oew films become superconductive at 

87 degrees Kelvin, 10 degrees above lis* temperature of liquid nitrogen, and ha ve critical 

current densities well above the minimum 

considered practical for applications-. 

"Superconductive thin films on silicon 

with critical current densities u high as 

these will have significant applications ta 

future production of Wgb-speed el<xtror_e 

devices." Mys Venky VerJulesaa. the Bellcore researcher who led the team. 

Bellcore used pulsed-laser technoiofy it 

pioneered In the last two years lo lay a yttrium-barium-copper-oxide film 00 silicon 

wafers having buffered layers. The team 

first deposited a superconducting film directly 00 silicon a year ago. 

Three problems bad to be overcome to produce quality films on silicon. Superconductive film reacts chemically against the silicon substrate at tbe 650 decree Ctetrl_T_de 

temperature needed to deposit the film. Ia 

addition, superconductive films were prone 

to cr?ck. and researchers had difficulty 

putting propcrlyoriented films oo si!icon. 

A team at Nippoo Electric. led by Yotehi 

Miyasaka. developed a buffer layer between 

tbe film and tbe substrate The buffer consists of magnesium aluminate grown directly 

on silicon by chemical vapor deposition and a 

subsequent layer of barium Utanale deposited by sputtering.
